Lemon curd. It's sold out in about every store.
I found one store that had a few jars of lemon curd. Not the best brand but I was desperate. It's my addiction. LOL
It was of course way to sweet and no tart lemon taste. I put it in bowl and added fresh squeezed lemon juice a little at a time until I got the perfect taste. It took a lot of lemon juice and a little salt. I think this is one reason so many don't like some foods. They get the first taste from a low quality brand so it's a no thank you from now on. If you want to try a new food buy the more expensive which is usually the higher quality first then buy down until you can tell the difference. There is usually a middle ground.
