When the prawns are peeled, do not throw away the shells or the heads, if you don't have many, you put them in a bag and store them in the freezer and when you have more they are fried in oil for 5-7 minutes, drain and store the oil in a jar and store in the refrigerator.
Step 2
Every time we have to make a paella, a rice, a fideuá, or a fish stew, we use it to make the sauce and that will give it a very rich seafood flavor.
Step 3
I used the shells of a kilo of large prawns and half a liter of extra virgin olive oil and a large jar came out, which I keep in the fridge and use it every time I have to make a dish that includes fish or seafood.
Step 4
You can also make that same oil with prawns or with both mixed together.
