Just watched Inside the Factory- Fish Fingers and they had a segment with Miguel Barclay making dishes using ONLY frozen ingredients (fish, meat, mash, veg, etc.).
Bizarrely, he seemed to be using “pellets” of bought frozen cheese sauce. I’m intrigued- anyone ever seen this for sale? I’ve googled to no avail. I mean, I know you can freeze home-made roux-based sauces, but I’ve never seen frozen pellets before.
