Pepper, sugar, coffee, tea and cacao o.a. were used (after the invention of
the wet plate in 1851) for leaving the sensitised wet plate negative more or
less sensitive after preparation. The general idea was to keep the
collodium-emulsion moist and open for developing, fixing and washing after
exposing ("dry collodium" plates).
These processes are also known as "culinair processes".

Soak them for at least 15 mins.

Rinse them for 15 mins. Cacao needs a washing aids (fat).

BTW. Those "toners" will only affect the gelatine layer and (only when using
baryta papers) the baryta layer.
So basicly only the highlights will be affected.
In my experience tea will produce a weaker effect, but more even than coffee
or cacao.
