I was talking to a friend about this who never heard of synesthesia, and though I was messing with him. I challenged him to write 50 random words on a piece of paper to which I would add colors. He took the paper, and a month or so later he read each word, to which I was able to flawlessly respond with the corresponding color. He did my chores for that week (we were roommates at that time).
That’s basically the only time it somewhat benifitted me. The rest of the time it’s people asking what color their names are whenever the topic comes up :)
I make my own hotsauces and chili salsa’s. You can go crazy with recipes, while it can’t really go wrong. I also give them to friends who love them.
A friend of mine makes his own ciders (apple or pear). Very cheap to make with minimal investment. Easy to learn, hard to master.
I’ve been looking into making cheese, which apparently is also easy to do, and only requires some special cloth so low investment too.
If you’re not into food/drinks; my gf crochets and knits. She learned it from youtube, and can make some cool stuff!
