I'm wondering about using a Randall the Enamel Animal to experiment with flavor combinations before mixing up a whole batch.
For example, obviously the flavor of hops comes out nicely with one of these, but what other ingredients are going to work as well? Can I experiment with things like roasted nuts, coco nibs, etc using a Randall or won't the flavors come through?
I assume that the most effective ingredients will be those that have water soluble flavor compounds (I believe most herbs fall into this category). It would make sense that fat soluble compounds (cardamon, most spices, etc) would not work well. I'm not sure about alcohol soluble things (tomatoes, peppers, etc)..
