On my first try the foil stuck and was almost impossible to remove and the bars crumbled. We liked these but wanted bars instead of trail mix, so I didn't give up. Consistent success were achieved after several experiments. My changes: I used walnuts instead of the peanuts so I added 1/2 tsp salt, & 1 Tbs flour, also 1/4 C raisins. Mix all the dry ingredients well. The 5 Tbs corn syrup measurement was changed to 1/4 C into a 2 C measurement cup, adding 1 generous Tbs Almond butter. Microwave this for 15 - 20 seconds and blend well with a small whisk, add in an egg white and whisk some more, pour over the dry and mix well. Pour into the 8 X 8 pan lined with plastic wrap generously coated with olive oil, cover with another piece of wrap coated with the oil, pack down paying particular attention to the corners and edges, remove the top wrap and invert onto a greased cookie sheet, again packing and forming. Remove the wrap and cut into 16 (4x4) pieces with a large chefs knife (keep the knife clean). Baking for 22 min in my oven is just right. Remove and cut again, keeping the knife clean and push the edges of each bar together. Slide the knife under to loosen and separate, work the edge of the bars together, cool.
