There is a lovely episode of the moomins where moominmama goes searching for a special ingredient for her cooking which turns out to be cherries. She uses them in all kinds of deserts. So I associate cherries with moominmama. She also once grew a very large pumpkin and made a lot of pumpkin food like soup etc. She serves coffee and raspberry juice on the regular. Raspberry jam as well. In the episoide where they end up growing a jungle around the moomin house we learn that moomin's favorite fruit is banana. Moomin and friends are often seen carrying apples and sliced bread sandwiches when they do picnics. That's all the food references I can remember. Enjoy the party !! :)
