Weird emergency baking questions: I'm making cherry pie, but I realized I'm out of arrowroot and cornstarch. Usually I simmer frozen cherries with a little lemon juice, sugar, and one of the aforementioned thickeners. I have agar, but I need to boil it with a liquid first and I don't have cherry juice (or any other appropriate type of juice). I opened a bottle of merlot for the pasta sauce I made, so I can use that as the liquid, but I'm not sure if it will taste weird. Should I just use water, or is wine a better option?
