Coke and Hershey both tout their age in advertising, so they might be interested. I know from losing a trivia question on putting the age of several cereals in order that Quaker Oats is the first trade-marked breakfast cereal (1877), followed by Kellogg's cornflakes (1895) and Post Grape-nuts (1898).
M&Ms were created as chocolate that wouldn't melt specifically for the military in WWII and weren't available to the civilian market until after the war.
There are lots of food items that have been around forever: Hershey's cocoa, Gold Medal flour, Calumet baking powder, Arm & Hammer baking soda. Jell-O. Now if we could figure out how Peggy could make a bomb out of them.

Apparently there was an explosion in a chocolate factory a little while ago, but that seems more of an industrial accident. And all the jello bomb info I've found is for getting drunk.
Grain silos and mills are powder kegs waiting to go off, all that flammable particulate floating in the air.
Bon Ami cleaning powder would probably be delighted with product placement -- old-fashioned is a big part of their whole thing, and if they had no objection to product placement in
Arsenic and Old Lace,
out of the mouth of a dotty old murderess, no less, Agent Carter would probably be right up their alley.
I love that someone offhand mentions "bomb made from food" and 11 minutes later someone else offers three recipes.
Chocolate bars would totally be the thing. I mean, how much have Hershey bars changed? (Other than being smaller and more expensive. . . )
I love Bon Ami just because it looks so vintage. There is also Lysol, but considering what women were sometimes encouraged to do with it in the early part of the century, I am not sure that they would want that.
Details, Sophia?
They suggested Lysol would be good for douching.
