It’s been a while since I’ve had Kerrygold so I can’t confirm that the taste is exactly the same but it’s probably similar.

I had to look at a lot of stores to find it! 🙂 Unfortunately, the local dairy that made the BEST cream and buttermilk for making butter, clotted cream, etc, shut down last year so I started a new search. It’s not always easy to find. I’ve had luck with brands at my local co-op, Whole Foods (Organic Valley), and every once in a while one of our regular grocery stores.

You can definitely add a flavoring. I’d mix it in just after doing the ice bath, it won’t take too much mixing to get the flavor incorporated. You could mix by hand or with a mixer, just mix on low until it’s just incorporated (or just smush it in with your clean hands).

I’m so glad you liked it! Cultured butter is the BEST!

Real butter is the BEST! And fun to make, too. I always use buttermilk but if you try using yogurt I’d use plain, full fat, natural, organic yogurt without added ingredients. Try using the same amount that’s indicated for the buttermilk. Let me know how it turns out!
