Welcome, Sandra. You're in for a ball visiting this forum, it's a great place.
It's a shame about the flops, but, as you will read as you go through the various threads, many flops can be turned around into something different that is a real hit - i.e. jam that doesn't set becomes a dessert syrup, etc.
I totally agree about the lemon custard, isn't it just the best thing - and so easy!!
Have you tried any of the various mayonnaise recipes yet - great time for experimenting with these whilst we still have the summer weather.
