Carl Sagan once said that in order to make an apple pie from scratch, you must first create the universe.
I suppose the same is true if you want to make ice cream from scratch, too.
It’s very important that you do this all in the same universe.
Because, if you try to create apple pie in one universe and ice cream in another universe, you now have to bridge the two universes in order to have pie ala mode.
Sadly, the matter from the two universes will cause a massive anti-matter explosion.
So, skip dessert, and just have coffee.
