I love stuff like this, there is tepache in the fridge right now, and I was just bemoaning tossing some watermelon rinds (I grew the watermelon so wanted to use all but don’t like sweet pickles, which is the only thing I knew how to do with the rinds). Often there is so much flavor in the parts we throw out, just difficult textures.
I can get organic citrus here, also have some trees, though only the lime produces so far. Whole Foods produce section is solid and the organic stuff costs less there than in the grocery here. But I have done with non organic fruit so much tepache, oh well. Strawberries I do use only organic, those are so good and only about $1 more for the quart box.
Avocado pits are almondy in flavor also.
