Instant Pot Fish and Potatoes in Tomato Sauce with Olives

Ingredients

350 g potatoes about half a cm to 1 cm slices. New potatoes work well but floury ones will be lovely too and, as they tend to disintegrate a bit, they will thicken the sauce. You don't have to be too accurate about the exact weight of the potatoes

1 tsp sea salt

1 tsp vegetable stock paste

2 cod fillets (or any white fish)

Juice of half a lemon

10 green pimento stuffed olives, more if you want of course or none if you don't like olives

200 g chopped tomatoes

Black pepper, freshly ground

Soy sauce, a good drizzle

To serve

Lemon wedges

Parsley freshly chopped

Pour 250 ml water into the inner pot.

4.

Top with two cod fillets.

5.

Drizzle with the juice of half a lemon.

6.

Add about 10 green pimento stuffed olives.

7.

Top with 200 g chopped tomatoes (do not stir!).

8.

A few twists of black pepper and a good drizzle of soy sauce. Do not stir.

9.

Lock the lid in after making sure that the sealing ring is properly in place by pressing it down following its circumference a few times. Steam release handle pointing to Sealing.

*Terminology

Quick release (also called quick pressure release or QPR) means venting the steam as soon as the pressure cooking process finishes, i.e. moving the steam release handle from Sealing to Venting.

Natural release (also called natural pressure release or NPR) means letting the float valve pop back down of its own accord, so basically you don’t need to do anything at the end and can keep your feet up. If it takes over 15 minutes, you're ok to release the rest of the steam (by turning the steam release handle to Venting) that may be left in order to unlock and open the lid.
