Double batch of Greweling's sponge toffee - changes I made this time - heated the hotel pan in the oven at the lowest oven temp - turned off the oven and cracked the door for the cooling time.
Mixed the bicarb into about 60 grams of glucose so there wouldn't be any lumps - didn't wait the 5 minutes cooling before I added the gelatin and bicarb - just waited until the bubbles stopped.
Looks like it might just turn out to be the best batch ever.
Now I need to find an airtight container big enough to store it in until I can enrobe chunks of it and package it up for the fun fair.
Wish I had my Greweling's book with me here in Jackson, that looks like a fun delicious thing to experiment with...oh well, November will be here before I know it!
Happy to forward you the recipe if you would like.
