Cut the potatoes into slices a little less than the wide of for finger
Boil the cut potatoes for 7 minutes.
Remove the water
Place back in the pot
Melt a stick of butter. Do it in a separate pot and added it to the lemon juice. First time I made it I put them on top of the potatoes, but now I prefer to mel them and added to the lemon mix.
Blend the lemon juice with the serrano peppers, butter and 1 teaspoon of salt.
Pass the mixture of serrano with lemon through a sieve.
Place the mixture of serrano, butter and lemon with the potatoes, mix and let the potatoes cook in the juice for about 5 minutes.
Separate the potatoes on a tray.
Place the oven tray in the grill for about 3 minutes.
Watch so that they are not going to burn.
Sprinkle finely chopped parsley for garnish and flavor
