Bill of Materials for 1 Pack of Reese's Peanut Butter Chocolate
Ingredient Weight (in g) Percentage Weight Assumptions
Milk Chocolate* 56.70 0.57 2 ounces of Chocolate is needed as per the instructions. (1 oz = 28.35g)
Peanuts 21.00 0.21
It takes 540 peanuts to make 1 jar of 12 ounce peanut butter. In this case, we need 1 cup
which is 8 ounces, which means we need 360 peanuts but divided by 6, we need 30
peanuts. Each peanut is about 4.5-5 g. We use this to come up with 30*5=150g.
Sugar 18.71 0.19
The recipe states 1/2 cup for 12 buttercups, so that's 1/12 cup for 2 buttercups. (1 cup = 8
ounces = 226.796)
Dextrose 1.00 0.01 No data is available. This is just an estimate!
Salt 0.18 0.00 1/4 teaspoon is 1.05 grams. Divided that by 6.
TBHQ 1.00 0.01 No data is available. This is just an estimate!
Citric Acid 1.00 0.01 No data is available. This is just an estimate!
TOTAL 99.58 1.00
