dried meat
脯 centers on preserved meat, specifically dried meat. It refers to meat that has been dried for storage or consumption.
脯 combines the meat radical ⺼ with 甫, which likely contributes the sound. The character originally referred to dried meat, and the meat radical indicates the semantic category.
The meat radical ⺼ on the left and 甫 on the right can be remembered as meat (⺼) that has been spread out (甫 suggests a flat, extended shape) to dry, resulting in dried meat.
For フ, imagine a piece of dried meat that is so tough you have to chew it with a 'fu' sound: fu -> フ, as you work through the dried meat.
