Tuber magnatum

I was thinking that after inflating it you could displace the air with helium, but I don't know how much the balloon itself weighs so I don't know if that will do the job or not. 

 

One cubic meter helium can lift about 1kg or put another way, one cubic foot of helium lifts  28.2 gms, around an ounce.  I rather suspect a balloon of bread would weigh way too much and presumably it would be porous. Wouldn't it be cool if you could float a pomme soufflee, but that too is way too heavy?  So I am stuck looking for a taffy balloon recipe!

      I’ve been getting poor results with an old Betty Crocker recipie for Pecan Sticky Rolls.  The glaze starts out smooth, but ends up crystallizing and I don’t know if it is the recipe, my technique, or something else.
       
      It specifies 1 cup brown sugar and 1/2 cup margarine (I substitute butter), melted to boiling, then add 1/4 cup dark corn syrup. That is poured in a pan with Pecans and the rolls are placed face down and the whole thing baked at 350 after a second rise.

      I am trying to work on making some chocolates for my diabetic sister. As the sweetener, I used Swerve, an erythritol-based sweetener that supposedly behaves like sugar (and that my sister likes.) I added it to my standard milk chocolate recipe from Chocolate Alchemy- http://chocolatealchemy.com/recipes/dark-milk-chocolate-45 It came out of the melanger fine and set up OK. But, when I went to temper it, it would not melt! Even after an hour at 140F, it was about the consistency of peanut butter. 
       
      Has anyone worked with Swerve and have any successful recipes? Or have any idea why it was so viscous?  The stuff is darned expensive, so I don't want to experiment too much.

      @Smithy Your request gave me the imputes to finally word-process the recipe. My DW use Excel, which drives me to distraction.
       
       
      Mom's Apple Raisin Walnut Cranberry Pie
       
      4 baking apples, peeled, cored, and sliced
      1 cup golden raisins
      1 cup walnuts
      1 cup fresh cranberries
      1/4 cup flour
      1 cup sugar
      2 tablespoons margarine or butter
      2 pie crusts to fit a 9- or 10-inch pie pan
       
      Heat oven to 425F.
      In a large bowl, mix the first four ingredients.  In a small bowl, mix the flour and sugar together.  Sprinkle the flour/sugar mixture over the large bowl, mixing lightly with fingers.  Place first pie crust
      into pie pan, pricking with a fork.  Pour the fruit mixture into the pie shell.  Dot with the margarine or butter, then cover with second pie crust, crimping
      edges together and making sure top crust is vented.
       
      Bake at 425F for 15 minutes, then turn down oven to 350F for about 45 minutes.

      Is there any recipe from the modernist universe or any other galaxy to make ketogenic (low carb) puff pastry and strudel type doughs?  Unusual ingredients OK.  There must be a way...

      I have a nice recipe for Lamb shanks Rogan Josh. The recipe uses Greek style yogurt and stock along with the various spices and a long slow braise (3 hrs plus)
      7 out of 10 times the result is that the sauce has the appearance of having split the yogurt from the stock.
      It does not seem to affect the flavor at all, its just the appearance.
       
      Is this the result of cooking at too high a temperature at some stage during the cook?
