I have an ice cream machine because I now live somewhere where an occasional-use appliance does not make me screamingly mad about a lack of space.
Yesterday I made mince pie ice cream.
Take two mince pies; I used ones from Baker’s Delight. Pry them out of the despairing hands of your mince-pie-loving husband, and prepare to put up with the scolding of said man about how you’ve desecrated the poor things. Put mince pies into a whizzer of some sort and reduce it to crumbs – or chop finely, I guess.
Make vanilla ice cream; add the crumbs for the last five minutes of churning.
