They were on sale.
I can never walk away empty-handed from a produce sale. It’s equivalent to a shoe sale in my mind.
I had no idea what I would do with all the lemons when I bought them. It didn’t stop me. I have a healthy supply of recipe books. Plus there is always the internet.
The problem I’ve found is that most recipes only use 1 lemon. After a week of where I made 2 lemon pastries and 1 dessert, I still have more than half a bag of lemons left.
