• 1 lemon
• 1 carrot
• a bundle of tarragon
• butter ca 100g
• salt, pepper

How you do it

• wash the spinach
• peel the onions and carrots and slice them
• wash/rinse the tarragon
• prepare the fish
• wash, rinse and dry with paper kitchen towels
• salt/pepper on the in and outside
• stuff the fish (if possible) with some of the tarragon, a slice of lemon and onions
• peel the potatoes and cook for 15-18min in salty water
• rinse and let dry/cool for another 15min - maybe smash them a little bit in the pot
• while waiting, melt the butter with a bit of tarragon and a slice of lemon
• preheat the over to 200C
• put the potatoes into the baking pan 
• melt the butter with a bit of lemon zest or a slice of lemon and some of the tarragon.
• pour over the potatoes 
• sprinkle the potatoes with salt and pepper (preferably rock salt or crystalline salt)
• bake for 30min until golden brown
• remove the pan from the oven and let it cool down for a few minutes
• turn the heat up to max e.g. 250C

• if the sea bass needs more seasoning, do it now. 
• add the olives, bay leaves and lemon slices to the pan
• Then place the sea bass (skin up if it's filets) over the potatoes and return the pan into the oven for another 10min or so

For the spinach

• in the sauce pan melt butter and put the sliced/cut onions into it until they become translucent
• slice the garlic and add it to the mix
• then add the spinach and cook the whole this for ca 10min. The spinach will "collapse"
