I've wanted to gift curd (add to my holiday baskets), but I only see recipes say to keep in the fridge which has kept me from gifting. However, when you buy it's canned (but may be filled with all kinds of junk I don't know).
If you know how acid your lemons are (like you pH test your lemon juice) . . .
you can home-can you home-made lemon curd. Fresh lemons vary in acidity, and since lemon curd has LOTS of butter and egg in it (at least the good ones do!!!) you need to have lemon juice acid enough to preserve it properly.
If you DON'T know the acidity of your lemons, please use this recipe
and here is a link from Utah State University Cooperative Extension. . .
that will pull up an Adobe file ( .pdf file; you will need Adobe Reader) and it uses bottled AND fresh lemon juice, so you get the fresh of your home-grown lemons and the guaranteed acidity of the bottled lemon juice:
I think it was at Williams Sonoma's website where I saw a chef using a Vitamix to make Lemon Curd.
I saved the video on my desk top but it doesn't tell where it's from. I hope if you have a Vitamix and search at Williams Sonoma that you will find it.
