Seismic Shepherd's Pie

Shepherd's pie is comfort food at its most elemental: braised lamb under mashed potatoes. When the mashed potatoes are made from Seismic potato at 50,000 SHU, every forkful of fluffy, buttery topping carries cayenne-level heat. The filling stays savory and mild. The contrast is the whole point.

Ingredients

  • 4 Seismic potatoes (SS-POT-03), peeled and cubed
  • 4 tbsp butter
  • ½ cup milk
  • 1 lb ground lamb
  • 1 onion, diced
  • 2 carrots, diced
  • 1 cup peas
  • 2 tbsp tomato paste
  • 1 cup beef broth
  • 1 tbsp Worcestershire
  • Salt, pepper, thyme

Instructions

  1. 1

    Boil Seismic potatoes until tender. Drain and mash with butter and milk. Season with salt.

  2. 2

    Brown lamb in a large oven-safe skillet. Add onion and carrots; cook 5 min.

  3. 3

    Stir in tomato paste, broth, Worcestershire, and thyme. Simmer 10 min.

  4. 4

    Add peas. Spread mashed potato over the top, creating peaks with a fork.

  5. 5

    Bake at 400°F for 25 min until golden on top.

Tips

  • Fault Line potato (10K SHU) for a milder version.
  • The peaks brown first — creating a map of crispy capsaicin-rich bites.
Science Note

Mashing breaks potato cell walls and releases amylose starch. Capsaicin binds to the butter's milkfat in the mash, creating a fat-soluble capsaicin delivery system. The butter-capsaicin complex melts into the lamb filling as the pie bakes — heat migration downward.
