Whenever I make ice custard or cream (with or without eggs) the dessert turns out icy instead of creamy, no matter the recipe. I have an ice cream maker that uses a bowl one puts in the freezer and try to use full fat dairy products. Any tips?
This ice cream food science page suggests leaving the mix to chill in the fridge overnight before putting in the ice cream maker. We try to do this and get the mix thoroughly chilled.
Our other thought is that perhaps you should experiment with the mixing time. Perhaps you are freezing the ice cream for too short a period in the ice cream maker - leaving it under-processed when you put it in the freezer, where it will develop more ice shards.
That is just a guess, though, since it seems like your question shows that you are already addressing our first response - more fat! Fattier ice cream is in general much easier to get smooth and creamy than lowfat homemade ice cream. More suggestions for Jessica on creamy homemade ice cream?
