Hello all-

So here's the story. My family and I went blueberry picking yesterday near Mt. Monadnock in SW New Hampshire. Amazing views and blueberry bushes just dripping with gorgeous fruit. Seems to me there are some eGullitiers with some awesome ideas for updating the traditional approach to jams/jellies etc. Here's what I did and a few questions.

I wanted to create a "purist" blueberry jam. Just fruit and sugar and less sweet than traditional jam Fished around in the Internet and tried this. Just 2 ingredients: blueberries and sugar at a 2:1 ratio of fruit to sugar (many recipes call for 1:1). I now know I could have gone even less on the sugar to really bring the true blueberry flavor more to the forefront. I elected to omit the pectin, which most recipes call for. I followed the canning directions on the bottom of the 1/2 pint Mason jars.

My recipe was:

12 cups freshly picked blueberries

6 cups sugar (I might try 4 next time)

Sugar into large sauce pot/stock pot

When the sugar melts, add all fruit and stir

Continue cooking fruit, regularly stirring, for 20-30 minutes, until it reaches about 200 degrees

Using a canning funnel, fill (not to the top) super clean jars and apply rim/cap, just until on - do not over tighten

Filled jars into simmering water, with at least 1 inch water over top of jars

Bring to boil

Set aside for 5 min.

Remove carefully jars from water and allow to cool for several hours.

Once cool, push on each lid. They should have no give or pop when you push on the top.

How would you change what I did? Other great ideas for abundant blueberries? Blueberry jalapeño jam anyone???

Two thoughts come immediately to mind: first, cooking the fruit for 20-30 minutes is going to mute the flavours; you want to bring it up to temp as quickly as possible (without scorching) to keep the maximum flavour. Second, you want a "modern" approach, "updating the very old art of preserves," why would you omit the pectin? Pectin is a great tool for controlling the final texture of your jam.

I've done blueberry lavender jam before, came out great. Just be careful not to go overboard on the lavender or you'll end up with something that tastes more like bubble bath. If you're not looking to make huge quantities and are planning on using the jam up within a couple of weeks, you could try doing some in the microwave. I did that with the apricots I had left over after making my regular jam recipe. Just cut up with half sugar to amt of fruit, juice of half a lemon, and microwave until it comes up to 220 degrees or so. It took about 10 min and I stopped it twice to stir. I put it in a really clean jam jar and let it set in the fridge. I didn't do the water bath, I kept it in the fridge and it was gone within a week or so. With blueberries you definitely could reduce the sugar to 1/4 the amt of fruit and it would work fine. Good Luck!

Last winter, I was "gifted" with two cases of Seville oranges. Not knowing what to do, I ended up making marmalade with them, put them up in 250 ml jars, and stuck them on a shelf in my store.

They sold, all of them, within two weeks.....

I now do a batch of 72 jars every few months, and am dabbling with strawberry jam and blueberry jam.

Vancouver area has earned a reputaion for blueberries, and I can can pick up b'berries for CDN $1.90 per lb from many growers.

I like to put in 1/5 of the b'berrywight of 3 time blanched lemon peel in the jam.

I'm now working on a mincemeat to put up in to jars for the upcoming Christmas season.

Maybe I do cheat a bit, I have a 15 qt electric steam kettle in my kitchen. Not very powerfull, but no hot spots and no scorching, it's perfect for small batches of jams......

I made freezer blueberry jam this summer. I followed the directions on the pectin box, however instead of lemon juice I used cranberry and at the very end before it sets up I added more blueberries (I wanted to have big whole blueberries). Adding in the whole blueberries at the end decreased the sugary sweetness and amped up the overall blueberry-ness. I also added cardamom which was wonderful with the blueberries. I think nutmeg might be good, too.

This summer I have also made raspberry jam with vanilla and lemon zest- very nice, plum jelly- amazing, spiced plum jelly- not a big hit. Maine has peaches in season now. I'm going to do peach and ginger jam and perhaps a peach almond if I can figure out a good way to do it.

Don't throw away that watermelon rind - pickle it.

Great to crack open a jar in the middle of the Winter and remember those hot Summer days.

To add more body to the blueberry-ness of the jam, you could add dried blueberries.

As for updating in the technical sense, I second the addition of pectin. Pectin is a naturally occurring carbohydrate which helps the jam to set with less cooking. Therefore, the jam will taste more "fresh" than a long-cooked jam.


Filled jars into simmering water, with at least 1 inch water over top of jars

Bring to boil

Set aside for 5 min.

Remove carefully jars from water and allow to cool for several hours.

For consistently safe water-bath processing, after the water returns to the boil, continue to boil for 10 minutes (1/2 pint and pint jars) or 20 min (quart jars). After the appropriate length of time, turn off heat, then let the canner/pot settle for about 5 minutes before removing the jars to cool in a draft-free location overnight.

The equivalent of a tiny pinch of salt per litre/quart of finished product really makes flavours pop, in sweet preparations.

Even the highest quality/feshest blueberry preserves often have a sort of muted/flat flavour, and a little salt takes care of that (perceptionwise, I'm talking about an amount that is right the liminal level, not enough to wreak havoc with the actual flavour, or anybody's blood pressure).

I'f you're going with a 'purist'/modernist take on this, you might want to try straight capsaicin (although you have to take care with it), rather then actual jalapeño(s).

And, since citric acid has been something I've been playing with recently, I'd consider that as an option to to add a bit more brightness to the flavour (if you wanted that), without adding additional liquid, or bringing in other notes (e.g. lemon), that would take you away from the streamlined 'just the blueberries' approach.

If you're okay with moving a bit a way from a 'purist' jam, cinnamon is great with blueberries.

"Peach Jam with Vanilla and Amaretto" was one of my great success stories this year.

I used a Pectin additive to minimise the cooking time, kept boiling to a minimum and kept the lid on to try an avoid loss of aroma.

It seemed to work so I will stick with it.

      What sorts of mustards do you like? The type of mustard I like is pungent without a hint of sweetness (fie upon honey mustards), but not too vinegary. Inglehoffer's Stone Ground tends to be rather good, but it's got a little too much vinegar (overpowers the taste of the mustard). What sorts of mustards do you like? Any brands? Or do you make your own?

      Sorta Secret Aardvark Sauce (Habenero Hot Sauce)
      I thought I'd submit my recipe which is a clone of a locally available sauce here in Portland OR called Secret Aardvark Sauce.
      Sorta Secret Aardvark Sauce
      1 – 14.5 oz can of diced tomatoes or roasted tomatoes chopped - include the juice
      1 – 14.5 oz of rice wine vinegar. Use the now empty tomato can to measure
      1-1/2 cups of peeled and grated carrots (packed into the measuring cup)
      1 cup of finely diced white onion
      1/4 cup of yellow mustard
      1/3 cup of sugar
      2 teaspoons of Morton’s Kosher Salt
      1 teaspoon of black pepper
      13 small Habaneros – seeded and membranes removed. (This was 2 oz. of Habaneros before cutting off the tops and removing the seeds and membranes)
      2 teaspoons curry powder
      1 cup of water when cooking
      5 or 6 cloves of garlic - roasted if you've got it
      Put it all in the crockpot on high until everything is tender. About 3 hours  Note: I used the crockpot so I don't have to worry about scorching it while it cooks. 
      Whirl in food processor – Don’t puree until smooth – make it lightly/finely chunky.
      Makes 3 pints - To can process pint jars in a water bath canner for 15 minutes
      I've thought about making this with peaches or mangoes too, but haven't tried it yet.

      Prawn Balchao is a very famous Goan pickle that has a sweet, spicy and tangy flavor to it. 
      For the balchao paste you will need:
      > 8-10 kashmiri red chillies
      > 4-5 Byadagi red chillies
      > 1/2 tsp cumin seeds
      > 1/2 tsk turmeric powder 
      > 1 tsp peppercorn
      > 6 garlic cloves
      > 1/2 tsp cloves
      > 1 inch cinnamon stick
      > Vinegar 
      First you will need to marinate about 250 grams of prawns in some turmeric powder and salt. After 15 minutes deep fry them in oil till them become golden n crisp. Set them aside and add tsp vinegar to them and let it sit for 1 hour. Now, make a paste of all the ingredients mentioned under the balchao paste and make sure not to add any water. In the same pan used for fryin the prawns, add in some chopped garlic and ginger. Lightly fry them and immediately add one whole chopped onion. Next, add the balchao paste amd let it cook for 2-3 minutes. Add in the prawns and cook until the gravy thickens. Finally add 1 tsp sugar and salt according to your taste. Allow it to cool. This can be stored in a glass jar. Let this mature for 1-3 weeks before its use. Make sure never to use water at any stage. This can be enjoyed with a simple lentil curry and rice.

      The basic formula for these cakes was developed by the wife of a mayonnaise salesman in an effort to help him out. I did a bit of research, and have found many variations. Early variants generally involve using less cocoa, which I cannot recommend. Later variants involve using cold water instead of boiling, adding salt, and additional leaveners. I personally do not feel that any additional salt is needed, as mayonnaise and that famous, tangy brand of salad dressing (sometimes the label just says 'Dressing') both contain a fair amount of salt. If you are using homemade mayonnaise or a low sodium product, an eighth teaspoon of salt may boost the flavor a bit. And, of course, somewhere along the way fans who prefer a certain salad dressing over mayonnaise started using it to make this cake. Nowadays, the Hellman's website has a different formula -one with added eggs and baking powder. I have not tried this newer formulation.
      Some versions of this recipe specify sifted cake flour. This will result in a very light cake with virtually no structural integrity, due to the paucity of eggs in this recipe compared to a regular cake. Cupcakes made this way give beautifully light results. However, every time I try to make a traditional 8" double layer cake with cake flour, I experience collapse. I recommend AP flour or at least a mix of cake and pastry flour.
      I have never made this with a gluten-free flour replacer. This recipe does not have very much structural integrity and as such does not make a good candidate for a gluten-free cake.
      I have made this cake many times, the type of sandwich spread you choose will affect the outcome. Made with mayonnaise, the cake has a good chocolate flavor and moistness. Made with that famous, tangy, off-white salad dressing that gets used as a sandwich spread, the cake has a subtle bit of extra brightness to the flavor. If one chooses to use a vegan mayonnaise, the result is tasty but lacking a little in structure; I would bake this in a square pan and frost and serve from the pan.
      The cocoa you use will also affect the flavor.  For a classic, homey flavor use a supermarket brand of cocoa. To add a little sophistication, use better, artisan type cocoa and use chocolate extract instead of the vanilla extract.
      Supposedly, the traditional frosting for this cake should have a caramel flavor. Look for one where you actually caramelize some sugar first. Modern recipes for the icing seem like weak imitations to me; using brown sugar as the main flavor instead of true caramel.
      Chocolate Mayonnaise or Salad Dressing Cake
      makes enough for two 8" round pans, or a 9" square (about 7 cups of batter)
      2 ounces/56g unsweetened, non-alkalized cocoa
      1 cup/236g boiling water
      1 teaspoon/4g regular strength vanilla extract
      3/4 cup/162g mayonnaise, vegan mayonnaise, or salad dressing (the tangy, off-white, sandwich spread type dressing)
      10.5ounces/300g all-purpose flour
      7 ounces/200g sugar
      0.35ounce/10g baking soda
      Preheat your oven to 350°.
      Grease or spray two 8" round pans or an equivalent volume square or rectangle.
      Place the cocoa in a medium (4-5 cup) bowl. Add the hot water and stir with a fork to break up any clumps. Allow to cool down a little,  then add the vanilla extract and the mayonnaise or salad dressing spread. Beat well to eliminate lumps. In the bowl of an electric mixer or larger regular bowl if making by hand, sift in the flour and add the sugar and baking soda. Mix the dry ingredients to distribute evenly. Slowly beat in the cocoa mixture. Mix until the batter has an even color. Pour immediately into the pans. If making two 8" rounds, weigh them to ensure they contain equal amounts.
      Bake for approximately 20 minutes, or until the center of the top springs back when touched lightly. (The toothpick test does NOT work well on this moist cake!) Allow the cake to cool a little and shrink from the sides of the pan before removing. Removal is easier while still a little warm.
      Good with or without frosting.
      Good beginner cake for kids to make.
