Notes on cooking with Pumpkin & Apples

From Episode 12 – A brief breakdown of useful facts, techniques, & science info about cooking with pumpkin and apple.

Ingredients
  

Apples — Fast Facts

  • ~50–65 kcal per 100 g; fiber and many polyphenols concentrate in the skin.
  • Browning: oxygen + enzymes → brown pigments; slow with quick lemon, light salt water, or honey-water dip.
  • Set the texture: heat slices to about 160°F/71°C, then cool. Pieces stay tender but intact.
  • Good heat-holding varieties: Granny Smith, Honeycrisp, Braeburn, Cosmic Crisp.
  • Good for sauce/softer fillings: McIntosh, Cortland, Rome.

Pumpkin & Winter Squash — Fast Facts

  • Canned pumpkin: about 80–90 kcal per cup; solid fiber; orange color signals beta-carotene, pro-vitamin A.
  • In cans, “pumpkin” often uses dense moschata types (e.g., Dickinson, butternut) for silky purée.
  • Variety guide: moschata = silky purée; maxima (kabocha, red kuri) = drier and sweeter; pepo (sugar pumpkins) = classic look, variable water.

Why the Techniques Work

  • Bloom → Deglaze → Brighten: bloom spices in fat; deglaze to lift fond; finish with a touch of acid for clarity.
  • For browning: dry pumpkin cubes and roast hot. Use purée when you want silk, not sear.
  • Tart apples help structure: acidity strengthens pectin networks so slices keep shape in heat.

Pro Move — Preheat Apple Slices (No Sous Vide)

  • Quick Steam: basket over simmering water, covered 3–6 minutes to ~160°F; cool and blot.
  • Hot Syrup Poach: 1:1 water:sugar held near 170°F; 5–10 minutes after liquid returns to temp; drain, cool, blot.
  • Microwave Steam: covered dish with 1–2 tsp water; 50% power 2–3 minutes, then 30–60 second bursts to ~160°F; cool and blot.
  • Aim for 155–160°F at center; use uniform 1/4-inch/6 mm slices. Always cool/blot before pies or galettes.

Takeaway

  • Choose dense squash for body, tart apples for lift, and let heat plus acid do the rest.
