  3. Cover and keep in the refrigerator for 1 hour.
  4. Brush a little olive oil over the fish fillets, on both sides.

Lemon Butter Sauce:


  • Butter- 1/2 cup or 125 gms
  • Lemon juice -4 tbsp
  • Garlic cloves-4 minced
  • Salt – to taste
  • Black pepper – to taste
  • Chopped coriander leaves -1 tsp
  • Egg yolks -2 (optional – for hollandaise sauce)


  1. Melt the butter over medium heat.
  2. Add chopped garlic and saute for a minute.
  3. Now add the lemon juice, salt, pepper, and coriander leaves. Allow it to boil.
  4. Stir and cook on low flame for about 10 minutes.

To make hollandaise sauce: ( this is a more delicious and thick lemon butter sauce variation)

In a heat-proof bowl -mix the egg yolks with lemon juice, salt, pepper, and a tablespoon of cold water. Cook this over a double boiler while whisking.

As it thickens, spoon in the melted butter (remove and keep aside the garlic) and continue beating the mixture. If the sauce gets flaky or forms clumps, quickly add another spoonful of cold water and keep stirring.

Add the garlic and chopped herbs of your choice. I prefer adding coriander leaves.
