Flavor Variations

Learn From My Mistakes

• Problem: Overcooked, mushy lentils. Fix, lower the simmer and start checking tenderness at 20 minutes.
• Problem: Bland broth. Fix, sweat vegetables until soft and aromatic, taste before adding lemon and adjust salt.
• Problem: Watery texture after refrigeration. Fix, reheat gently and simmer uncovered a few minutes to concentrate, or add a quick mash of some lentils to thicken.
• Problem: Dull lemon flavor after reheating. Fix, add fresh lemon juice just before serving to revive brightness.

Leftover

• Turn leftovers into a lunchtime bowl, heat and top with a fried egg for a textural contrast.
• Use as a base for grain bowls, spoon over cooked rice or quinoa and add raw or roasted vegetables.
• Blend partially for a thicker spread, cool slightly and use as a warm dip for vegetables or toasted pita.
