Freezing with or without the cream

Like the poster below, I too am now relying on my slow cookers (I have 4 too!) rather than the oven in order to keep energy bills low. I have previously cooked some of Delia’s recipes in the slow cooker successfully, including baked Hungarian pork chop from ‘One is Fun’. I usually double the ingredients to cook for 2 but this time I’d like to batch cook and freeze some. Is it possible to freeze this with cream/yogurt, or is it better to freeze without and add this when reheating? Thanks.
