Butter needs to be “frozen” if you want to bring back, says here:
BTW, for cheese, it said pasteurized cheeses:
With cheeses, it’s the consistency that makes the difference. Only hard, semi-soft, and pasteurized cheeses are allowed over US borders to live the American dream of being eaten on a Wheat Thin. Raclette, emmental, comté, brie, camembert are among those welcome, along with many other milk-based products like yogurt and butter. It’s those soft and runny cheeses like chèvre that are not allowed, or cheeses that contain any meat products in them.
The best cheeses and butter are the unpasteurized ones…
