Seriously...ideal topping additions
It's going to be a struggle to find space for dessert after, so it should be included for psychological purposes. Whatever you choose, it can't be anything too moist (hmmm....moist) as that would spoil the texture of an otherwise master class dish. So I propose lining one side with a simple row of 5 or 6 eccles cakes.
Seriously though...Yorkshire pudding is just an oven baked pancake. Personally I prefer savoury pancakes to sweet...so where's the problem?
