I always think frying things is a bit of a hassle, but once in a while, it's worth all that oil and all that clean-up.
These onion strings: definitely worth it.
Simple. Thinly slice an onion or two. Soak in buttermilk (or well, I used Swedish filmjolk) for an hour.
Toss with flour, that you have seasoned with salt and cayenne pepper.
And plunge into hot oil. Fry until golden. Season with more salt and black pepper.
