Brandade is a mixture of Mashed Potatoes, Salt Cod (Morue), Garlic, and Olive Oil, with a few other bits and pieces thrown in as desired.
It's always been on the menu at one of my favourite nearby restaurants, and I've been wanting to make my own version for as long as I've been a client; i.e. for decades.
I recently discovered this ready-made variety (above), so as I had a burning desire for stuffed Peppers (Haddock's is overflowing), I decided to see if it compared favourably to that of the restaurant. It did; and in fact it was fantastic.
I didn't think of taking a snap of my own cooked Peppers, so I've had to borrow one from Mr Google. Mine looked much the same, and was delicious.
There was a decent amount of brandade left over for lunch the following day (now, yesterday), so I made some simple fried fishcakes; also bloody delicious.
Any hollowed vegs can be stuffed with brandade, and all are superb.
You may not be able to buy the ready-made version above, but it's very simple to make.
