Traditional trifle was spiked with sherry and such. Just saying.
(Yeah, yeah, I know it wouldn't work with Monkey eating it.)
I am aware of the involvement of alcohol but am mostly keen on the cake aspect of the dessert. (So, here's a story about MIL who made trifle for family gatherings but never used alcohol. She and FIL went to a local restaurant that also had trifle on the dessert menu. They were not happy. So MIL asked the waiter to have the chef come out and then she gave him her traditional British recipe. [Note that she and FIL did immigrate from England in the 50s. She was a WWII child who spent some time evacuated to Wales during the Blitz. But her trifle recipe also included... Little Debbies.] And when I pointed out that Strawberry Rolls where not a traditional British food... well, the shade was strong.)
