Inspiration: Thanks to a sale on lemons a few weeks back, our fridge’s fruit drawer overflowed with this citrus staple, which is all well and good until you need to start using them up! So with that in mind, I made one of my husband’s all-time faves — Lemon Sour Cream Cookies.

With a subtle tang from the sour cream and an acidic hit of the lemons, this recipe is excellent. This particular one comes from America’s Test Kitchen’s The Perfect Cookie cookbook. (If you like making cookies, this book is well worth the money as I’ve never had a recipe of theirs fail — despite my best efforts. And no this is not a sponsored post, I just love this book.)

And I didn’t tweak a single thing!

Christie: These aren’t fancy cookies per se, but if the icing was piped on with care or sprinkles added on artfully, I can see Poirot indulging in one or two of these cookies as they aren’t overly sweet, and the sour cream is just unusual enough to make them interesting!
