# How-To:

# Expert Advice:

01 -
  • It fills you up without feeling heavy, thanks to the mix of two lentil varieties that cook at different rates for perfect texture variation.
  • The umami from mushrooms deepens every spoonful, making it feel more restaurant-quality than a weeknight dinner deserves.
  • One pot, minimal cleanup, and you'll have enough leftovers to carry you through the week.
02 -
  • Don't skip the browning step with mushrooms—those few minutes of contact with the hot pot create flavors that simmering alone cannot build.
  • If your barley isn't tender after thirty-five minutes, it's okay to add a bit more water and keep cooking; different brands behave differently.
03 -
  • Rinse your lentils and barley before using them; it removes excess starch and makes the final broth clearer and more refined.
  • The smoked paprika is doing more work than you realize—don't reduce it, even if you're tempted to lighten the spice load.
