Trials of cooking.....

I do try, truly I do..... my merangues are so huge it will take a week to get my blood sugars back to normal after one of these, and my little lemon drizzle hearts are not even heart shaped. I cook on an Aga it's great for everything but I find cakes a real challenge, if anyone has any tips, please take sympathy on me and hand them over.....quickly xxxxx
