Standard cans, C.... around 250ml....the idea is to have the two ingredients 50/50. No, have not tried coffee yet, did shaved choc, walnuts, berries ( defrosted, mashed, then mixed through, otherwise you will break a tooth...) and several liqueurs. I would think that , if you want to use coffee, maybe use a ristretto, as the more liquid you introduce in the mix, the harder the icecream will be. ; L)
