dairy products, whey, broth, fruit juice
酪 centers on processed liquids from animals or plants: dairy products like whey, broths, and fruit juices. The common thread is a nutritious or flavorful liquid extracted or fermented from a base ingredient.
酪 combines 酉 (a wine or fermentation vessel) with 各, which likely contributes the sound. The character originally referred to fermented milk products like kumiss, later extending to other processed liquids.
The left side 酉 is a sake jar, suggesting fermentation or processing. The right side 各 looks like a person sitting cross-legged. Picture someone sitting beside a jar, straining whey or juice from it.
For ラク, imagine a lucky person finding a jar of delicious whey: luck -> ラク, and the jar is full of dairy goodness.
