I recieved a double/magnetic sphere mold as a gift. I had asked for a model that has a dimple molded into it:

http://www.chocolat-...16408423.2.html

One pushes on the projection and it drops inside to make a small filling hole. Filling this mold is a matter of filling the bottom half to a certain level, cliping on the top and spinning it.

But since it was on back order the company substituted another mold that has a solid bottom half and a top with about a hole in the top of each cavity.

I am after making hollow spheres to be filled with a sugarless liquor filling that I can seal off easily, so my first question is, does it really fit the need? I ask the question because the original mold appears to have a slope to the hole that would make it easier to seal by dropping a small disk of chocolate in before topping with tempered chocolate. Additionally, the actual hole would appear to be smaller.

My second question is just how to work with it. I was told that to make a hollow sphere with this you fill it up and tip it out like any other mold, but I'm not sure just how one goes about doing that. The mold has several holes that run all the way through both halves, so just pouring chocolate on top of both would result in a real mess, not to mention that I don't think it would fill each cavity anyway. Using a funnel seems far too slow as the wall thickness would vary greatly from the first to the last cavity due to a longer cooling time. Does one fill the bottom, put the top on, place a card over the holes and hand spin it before a final tipping without the card?

I can return it and wait until it becomes available next year, but I wouldn't mind keeping it if it will work out fine.

David,

Do you have a picture of the mold you received? I can't picture it.

I have the mold you linked to and I find it great to work with and mold.

Here is a closeup of the top half of the mold:

There are 4x8 cavities each about one inch in diameter. The filling holes are 3/8" in diameter.

Note the hole that runs through the mold. There are four of these on each end of the mold. I'm not sure what they are for since there are alignment pins and holes on the top side of each half.

In school we used chocolate shells that obviously had come out of a mold similar to yours... but we didn't make them. So all I can tell you is that we did fill them up and top them off with chocolate and they were fine, especially once rolled in more chocolate and cocoa, you never saw the original hole.

They really should send directions with a mold like that. The only thing that doesn't sound like it'll cause a huge mess is to paint the shells... but that's only good for a few and very time consuming, and for sure you'd need more than one coat. Why don't you give them a call?

That does seem like a huge hole in the top. I have no idea why the 4 holes are there, unless it is for use with some form of mechanized device like a spinner.

The thing that appeals to me about the mold is that it is 1 inch. My sphere mold is 1 1/4 inches and I would prefer a smaller size.

I vote you keep it and report back on your success. I can send you some molded spheres from my mold and you can compare the filling and sealing of each.

How did you top them off? I can see it being easy if you have a filling that crusts over, but my original aim was to use them for a liquid filling with no sugar. I wasn't thinking of rolling them in chocolate or cocao but rather leaving them with the shine.

I did write back asking about how to fill the mold. The person told me to fill it to the top and then dump it as you would any hollow mold, but my problem is in the detail of how to fill it quickly enough without making a huge mess.

I had the same thought that the holes might be for a spinner, but it would be a real mess with the chocolate dripping out of the fill holes.

Here I was thinking that the spheres would be too small. I suppose a one inch ball might be easier to pop in the mouth and bite.

How thick a shell do you usually cast, and what viscosity do you use? What sort of fillings do you use? Do you ever use a pure liquid? That probably has an effect on how easy it would be to seal.

If I can get a good answer on how to fill them I might just keep it and take you up on your offer to compare.

I try to make the shell as thin as I can. I use my usual 815 bittersweet Callebaut which has 3 little drops on the front (ie lots of cocoa butter, makes nice thin shells).

I use them to hold fillings that are too soft for regular truffles. I have also just filled them with liqueurs. They don't last a long time with a liquid in them, but they are great for a party.

The sealing isn't too big a deal, I just take a piping bag with tempered chocolate and circle in towards the centre. In my mold the hole you punch in is slanted making it easy to prevent the chocolate from falling into the hole. Then I drizzle with a bit of contrasting chocolate to cover the piped chocolate, or dip the whole thing a couple of times.

Does anyone know where I can buy 815 Callebaut callets (as opposed to blocks)?
I'm having trouble locating a source.

My worry is the hole will be too large and not sloped which would make it difficult to pipe as you describe. Perhaps if it were extra thick it would work. Maybe a one drop chocolate or the equivilent viscosity created with a little water.

So you dip the molded chocolate too?

I use the blocks, I don't think it comes in the callets. Why not pipe yourself some small callets and drop them upside down into the hole then seal around them.

I do dip the molded chocolate too. You can run it over a wire rack to get a thistle appearance.

I took a class at Albert Uster with a Swiss chocolatier last year and we used some of these which had been premolded, by machine I'm sure. We filled them using special metal trays. There are 2 trays, one with smaller holes for filling and one with larger holes for bottoming.
When filling, we were taught to use a pastry bag and just go go go. It's a little sloppy. When you've finished, you use a bench scraper to remove the ganache that remains on top of the filling tray. Same sort of idea with the bottoming tray. Cover the whole thing with chocolate, scrape, and lift off the tray.
We coated them or decorated them in at least 10 different ways. They have a little seam around the middle which most would want to cover. Vosges uses these premade shells for their truffles.

Qzina carries the 815 callets.

I was hoping to use callets due to the easy tempering. With them all the same size you just toss them in and stir. JPW made it look SO easy. Now I have to decide if I still want the 815 enough to deal with blocks.

Would a solid disk float on liquor or flip and sink? It would work with sloping sides, but I'm not sure about straight sides. Or do you mean to pipe a cone shape that is just a bit larger than the hole? I suppose that might work, though I'm not sure how to pipe so accurately.

I have a truffle rack on my gift list, so I will be able to duplicate the thistle look I pictured in my class report.

The lady at Qzina said that the 815 callets were domestic rather than Belgin. Is there a noticable difference, or is it essentialy the same thing?

Google is a wonderfull tool. Is this what you used?

It's hard to tell exactly how they are built by the pictures. Are they just flat sheets, or do they have protrusions that fit down into each shell? I'm trying to imagine how it works to get a seal over the filling and I'm having a little trouble.

I don't care for the american Callebaut. I find it inferior to the Belgian.

We filled them with ganache and would put them in the fridge for about 10 minutes. Then we would just top off with chocolate in a cornet. I don't think you need your filling to crust over.... just that it's thick enough to support the weight of the chocolate without it sinking into the filling. If you were doing a liquor filling, maybe the 10 min in the fridge would thicken it up just enough to support the chocolate. Good luck.

David, those are indeed the trays we used. The filling hole is slightly tapered so that it fits just perfectly. The finishing hole is a bit larger and concave to cover the ganache entirely.

I keep thinking about how to cap off a bonbon filled with just booze. Layer upon layer of a light spray with an airbrush? A disk large enough to cover just the outside of the bonbon hole and then a final dipping to cover the fact that the "bottom" is a touch bigger than the rest? I dunno.

Which way are the holes in the filling tray tapered, inward like a funnel? Is it a flat sheet or does it have a stem that fits inside the hole? Could you draw a picture?

I had suspected that the finishing tray might be concave since it has to have a definite thickness to cover the ganach a straight sided hole would produce a cylindrical pillar. That makes it a bit tougher to machine and explains part of the reason it is so expensive.

I had an idea for covering the pure liquid filling. If I took a tapered countersink bit like this:

http://www.amazon.co...39?ie=UTF8&s=hi

I could possibly produce a sloping hole that would let a solid disc lodge in it. Then the sealing tray would cover that and form the rest of the sphere. I'll have to actually cast a mold to see what the spheres look like to see what I can do with them.

I ordered Callebaut 811 from Qzino since they don't carry 815 and the cocao percentage is within 2%. I should get that in a couple days and then I'll try the mold out. I was told by Chocolat-Chocolat to fill it with a piping bag so I'll give that a shot. I'll have to see how quickly I can fill all 32 cavities and if the first and last have significantly different wall thicknesses as a result of sitting filled for different lengths of time. The base formula might be liquid enough to work out.

From what the rep said I think that commercial uses have automated filling machinery that doses each cavity at the same time.

I was the chocolate instructor at the Wilton School of Confectionery Art for over 20 years. Meta McCall from Canada taught the course before me. She used to add a few drops of melted cocoa butter on top of the liqueur to seal the opening. Once the cocoa butter forms a crust, you spread chocolate on top to complete the seal.

No, I haven't tried that method but I'm sure it works. Meta was (is still?) an accomplished chocolatier. I have tried her alternate method of spreading chocolate on a strip of paper sized to fit over the openings of a row of de-moulded, liqueur-filled chocolate cups, pressing down to seal the sides, and peeling the paper off when the chocolate sets. It's not a perfect seal, but it does work on regular moulded hollow shells. I sometimes mould the chocolate shells in stiff-sided, gold foil cups, place a tiny raspberry in the bottom, fill (never to the top) with liqueur, and top with the chocolate-covered strips of paper. You can use a transfer sheet to do this. Again, it's not a perfect seal and you must warn people it is a one bite indulgence.

This method could certainly be used to seal David's spheres, then once set, add a little extra chocolate to reinforce.

We've used a truffle machine at work to fill the truffle shells during peak times. I will take a picture of it when I am in at work on Friday and post it so you can see what one looks like. During nonpeak times we simply use 'squeezy' bottles to fill the truffles shells with gananche. We have 2 plastic capping trays similar to the metal one that you linked to earlier. For small quantities capping the truffles with a piping bag works just as well.

That's what I love about this place, so many brilliant ideas! The chocolate paper strip should form a good enough seal for a second dip. The hole is small enough that it should be structuraly strong. I can use my really thick chocolate (two and one drop(s) for milk and dark respectively) to ensure a thick seal.

I checked the Albert Uster website and found that the shells they sell match my mold in diameter. That means I could probably buy their filling and sealing trays if I wanted. They are a bit pricey though, so I will probably start out by piping my ganache carefully and sealing with a pastry bag.

I want to try the three different non-sugar shell recipies in JPW's book to see which works out and tastes best. I have a co-worker who likes the filling semi-sweet, but with no crunchy shell and that gives me a personal chalenge to learn how.

I am only making tiny numbers of chocolates and have just started using the truffle shells after doing a one day course at my local college.

The instructor showed us how to use the plastic packaging for the shells to make your own filling template.

The sheet that sits on top of the moulds when they come out of the box has a few holes in already and if you are very patient and have a pair of sharp scissors you can cut out a nice little circle in each dimple to make your piping hole.

When you come to pipe in your filling you just sit this back on top of the shells and it traps any drips/smudges so long as the holes are not too big. I got tired cutting holes and just made a 4x4 shell template but it can easily be moved across the tray so long as you haven't been too messy with the piping.

I managed to wash it out afterwards but not sure how long it will last before it cracks or splits.

Its a good way to get started anyway!

Hi All,

I'm hoping someone has some experience with these.I bought new 2 piece magnetic truffle molds from JB Prince. The instructions are as follows.

2- Piece Magnetic Truffle Molds
Two pieces (bottom & top) are held together by magnets. Pour chocolate into holes on top and let set. Put filling in with pastry bag and tube. Then seal. When ready, separate top & bottom pieces. Each mold is 11" x 7". Produces 1" diameter round smooth. Filling holes are 3/8" across. Made in Italy of food safe, rigid plastic.


Should I pour the chocolate into the two halfs of the molds seperately, and then join them together, or fill the molds completely and let the excess chocolate drain out of the hole at the top.

Thanks,
Mark

Mark, is this the mold you have?

I haven't mastered it yet, but I have been experimenting and have had some success.

I have filled the mold with a pastry bag, though it takes long enough to do that the first cavity filled has about a minute more to set than the last. I have thought about filling the bottom half (without the holes) like a normal mold, scrape and put on the top. The problem with that is the surface is not smooth like a normal mold. Each cavity has a slightly raised ridge around it which catches any stiff scraper. The time delay can make a big difference in wall thickness from the first cavity to the last depending on the viscosity of the chocolate.

An alternative is to measure a small amount of chocolate into each cavity, slap on the top, put a cover over all the holes and spin the mold as you would one with no holes. Then while the chocolate is still a little fluid remove the cover put over a vibrating table and drain. That has the advantage of not having enough chocolate to create walls that are too thick, but you have to time it so you get hole cleared. I have used a drill bit to carefully open the holes in each cavity while the chocolate is just setting, but it's a bit messy.

I have thought of trying to build a multi-funnel top for the mold that would let me pour chocolate in quickly, probably with the mold on top of a vibrating table, but I haven't figured out how to do it easily yet. Perhaps soldering a bunch of brass tubing onto a brass sheet with holes drilled for the tubes. It's all a bit much work for me right now and I'm behind in my guitar cutter project so that comes first.

Something else you will notice is that surface tension on the chocolate will prevent it from just pouring nicely out of the holes. I found that I have to hold the mold inverted against a tray on top of a vibrating table to dislodge the exess chocolate.

I need more experiments to determine the proper viscosity to use and how long to let it sit in the mold. If it's too thin, the spheres will break in half when you open the mold. If they are too thick they aren't usable and they may not even drain at all.

My hope was to easily produce a large number of spheres so I could fill them with ganache for round truffles without having to roll messy balls of ganache. So far what I've used my few good results for are liquid filled liqour centers that don't have enough sugar to form a shell. I've used small disks with tempered chocolate as glue to seal them, then dipped the whole thing so it looks clean. They were a real hit.

Thanks Vanessa,

I really liked John's demonstration. He was using more conventional molds though. The question I have is when using a spherical mold will filling the mold, and then draining out the hole in the top cause too thick a coating.

I guess I could try filling them half way, putting the top half of the mold on, and letting it drain.
