Hmm First lot of jam tarts - fail. I thought it was a waste to not use the whole grape, and I didnt use enough geletin and its just a lumpy mess. The bases were not cooked properly and soaked the jam up overnight so its all soggy today. The flavours are there but they look a mess. I just dumped 3 in the air fryer to melt cheese on top, and then burnt them. Still edible, good tastes, but total mess. Not sharable.
I have another batch of jam setting now and I will try again. And if that fails, I have 2 more bags of grapes in the fridge.
