I should say that I really don't eat a paleo diet, I'm new to paleo, and I'm really liking the changes I've made. It's been a long, slow transition which has worked great for me, but has left me with a diet in which I eat grains pretty much everyday, I just crave them a lot. I always want to eat toast saturated in butter, which makes me think that it's the butter that I'm really craving, but nothing I've tried seems to satisfy my cravings like butter on sprouted grain bread or one of my mom's unbelievably good scones. I've been trying to find more fast paleo snack options that I can put butter on; butter on celery just isn't that good.
So far the paleo things I like with butter are:
chocolate (it's alright with butter:/)
I cook my eggs and sometimes fish in ghee and pour melted Kerrygold butter on oven-baked sweet potato fries. I suggest you try the latter because maybe the potatoes can help thwart your grain cravings.
For my kids and myself I use butter in place of anytime I would use mayo. So I soften and whip up Kerrygold for canned salmon/tuna. I also love butter on smoked oysters. I used to love smoked oysters on CRACKERS with butter but well...you know.
Paleo Pancakes! 2 eggs, 1/4 cup almond flour, pinch coconut flour, pinch baking soda, lots of cinnamon, and whatever else you want to throw in there. I smother them in butter, this is my breakfast on weekends ^_^
