3D chocolate molds: getting a clean seam

9 posts in this topic

Anyone have ideas on how to get a clean edge on a two-part 3D hollow chocolate mold (it's an egg)? I've tried:

- clipping the two mold halves together to dry while sealed

- letting two mold halved dry separately then heating the edges, either with a heat gun or by putting them on a warmed half-sheet pan


No matter what I do, the edges are not seamless.

I work with chocolate and molds every day, right now I'm winding down my Easter bunny/egg production.

Here are a few ideas on molds in general:


-I loathe, hate, detest, want to do terrible things to the people who make/sell molds where you have to "glue" or melt the halves together again.  It's a cheap cop-out, it's sloppy, and the joint is weak and prone to cracking or failing once packaged.  Ironically enough, Callebaut sells these molds, and I have a pictorial on another website showing how I band-saw the mold in half, cut some bottoms into it, and drill some locating holes into it to make it into a practical, two piece, clip together mold.  I've done this with about half a dozen molds now.


-Not much of a fan with the cheap thermo-formed molds, but they do work well for the first dozen or so times until the plastic cracks and fatigues.  Bear in mind that you will always get a rougher seam with these, because the plastic is not capable of bending sharp 90 degree or even sharper angles--this is usually where the the side of the mold meets the lip of the mold, and the effect is doubled when both sides of the mold are clipped together.


-Even with the best rigid molds you will still get  "flash" or minute feather edges of chocolate leaking out of the seam, regardless of how many clips you use.  This is easily trimmed off with a sharp, cold knife.

I've used some of the Parvoni moulds (they are sexy, such a shame they don't come in poly c).  I trim off the edges and clip them as a spinning mould as suggested.  I use bulldog clips rather than my spinning mould clips to try and keep the plastic as undamaged as I can.

      I've been asked to make a cake with an edible film strip style ribbon (NOT made of fondant) and I'm trying to work out a solution given limited time (2 weeks) and limited skills (a lifetime's worth of lack of decorating skills and attention to detail!).
      Ideally I'd love to use a chocolate transfer sheet ... but the only ones I can find are in the USA (I'm in Australia) and the shipping time makes that impractical.  I've been googling and not seen a decent alternative that I think I can do (actually I haven't even found something that is edible that I think looks good, even from professionals!!)!  Fondant would be the most obvious solution but I've been given the instructions of no fondant (but maybe they wouldn't notice a strip?!) ... but chocolate seems possible.
      Some ideas I've thought of and would love feedback ...
      Could I use old film negatives as a transfer?  Cut out the frames and then use the strips?   (am I going to kill anyone with chemicals?!!) Could I create acetone strips by trying to stamp/cut out something that sort of looks like a film strip?  Use it as a stencil instead? Piping on to acetate using an image behind as a guide?  I can't say I have very steady hands so am thinking it would be very wonky?!!! If I did the outline in dark chocolate would I need a white chocolate layer to make it transfer onto a buttercream cake?  
      I have a chocolate tempering machine, most likely to be using Callebaut 54% but could use Lindt 70%/85%/90%.
      I've really only used transfer sheets directly on to dipped chocolate, and acetate to create random curls for decorations ... I'm wondering about the logistics of getting the chocolate on the strips, keeping it shaped for the cake (I think the cake is square ... but maybe it might be round?!) and also transferring them on to the cake?
      (back up plan ... plain ribbon!!!)
      Would love any advice!  Thanks!!

      Looking for your opinions and experiences... I am planning to put some wire shelving in my chocolate & confections kitchen. The kitchen has a concrete floor. This shelving will hold ingredients, colored cocoa butters, and packaging. Wondering if I should get casters for this shelving... what are your thoughts on this oh so important question?  ;-)

      I've used Valrhona Ivoire white chocolate as a base for various ganache recipes for some time after failing to create a good ganache with other white chocolate including Callebaut, a brand I otherwise like.  Valrhona is expensive compared to other brands available here in England but Vente Privée offers it at a good discount several times each year.  There is a Valrhona sale this week: 
      That link is to the English site but I know the company operates in other countries. You need to become a member to buy from the site, not sure why but it is free and you aren't obliged to buy anything.  
      I've already placed an order, popular products sell out fast.  Since ordering I have read various posts in the Pastry and Baking thread that have left me wondering if I should be using Opalys as my white chocolate rather than Ivoire.
      Do any of you have experience of both variants of Valrhona's white chocolate?  I would be grateful for any advice you can provide on using them in baking or chocolate making.

      To all the chocolate lovers, manufactures and those experimenting with chocolate - have a happy day! So, to celebrate the day I have an order for a batch of Chocolate Peppermint Crisp Tarts for one of my retail outlets. What are you doing to celebrate the day?

      I have been looking for self-sealing plastic bags like Soma uses for chocolate bars. Interested in a rectangle vs. the squares Soma is using. Have not found anything at Gleurp or Nashville Wraps (but I may be using the wrong search terms).  Anyone know where to find these bags (in a variety of sizes) that have a flap with a bit of adhesive on the end for sealing the package?
      Any other chocolate bar packaging ideas that don't require going custom?
