mochi rice cake
餅 centers on the traditional Japanese rice cake, mochi, made from pounded glutinous rice. The meaning is specific to this food item.
餅 combines the food radical 飠 with 并, which likely contributes the sound. The character originally referred to a type of rice cake.
The food radical 飠 tells you this is something edible. The right side 并 looks like a stack of two round rice cakes, one on top of the other, ready to be pounded into mochi.
For ヘイ, imagine a heavy mochi rice cake: heavy -> ヘイ, and the weight of the mochi makes it satisfying to eat.
