Thandai is a chilled, aromatic milk-based drink traditionally enjoyed during Holi. Its signature flavor comes from a ground nut-and-spice paste (often including fennel, cardamom, pepper, and saffron) that’s blended into milk, then chilled until refreshing and fragrant.

What you’ll need

Core ingredients

  • Milk: whole milk gives the best body, but you can use low-fat (it will be lighter).
  • Nuts: typically almonds and cashews; pistachios are optional but add richness.
  • Seeds & spices: fennel seeds are key; cardamom brings sweetness; black pepper adds a gentle warmth.
  • Sweetener: sugar is classic; adjust to taste.
  • Saffron (optional but traditional): adds aroma and color.
  • Rose or kewra water (optional): a few drops can brighten the aroma—use sparingly.

Helpful tools

  • Blender or spice grinder
  • Fine strainer or muslin cloth (for a smoother drink)
  • Saucepan (optional, if you prefer warming milk to dissolve sugar faster)

Step-by-step: classic thandai

1) Soak the nuts

Soak almonds and cashews in warm water for 20–30 minutes (or in room-temperature water for 2–4 hours). This softens them so they blend into a smoother paste.

Optional: Peel the almonds after soaking for a silkier texture. It’s not required, but it helps if you’re aiming for a very smooth finish.

2) Make the thandai paste

Drain the soaked nuts. Add them to a blender along with fennel seeds, cardamom (seeds only if using pods), a few black peppercorns, and a splash of milk or water. Blend until you get a thick, aromatic paste.

Tip: Start with less liquid and add only what you need. A thicker paste extracts flavor well and prevents the drink from becoming watery.

3) Prep the milk and sweetener

You can do this two ways:

  • No-heat method: Use cold milk and stir in fine sugar, whisking until fully dissolved (may take longer).
  • Quick-dissolve method: Warm 1–2 cups of milk gently, dissolve the sugar, then combine with the remaining cold milk to cool it back down faster.

If using saffron, crush a few strands and steep them in a tablespoon of warm milk for 5–10 minutes, then add it in.

4) Combine and blend

Whisk the thandai paste into the sweetened milk. For an extra-smooth drink, blend the full mixture for 20–30 seconds.

5) Strain (optional, but recommended for a classic smooth texture)

Pour the mixture through a fine strainer or muslin cloth into a jug. Press or squeeze to extract maximum flavor from the solids. If you like a more rustic, thick thandai, you can skip straining.

6) Chill and serve

Refrigerate for at least 2–4 hours. Serve very cold. Garnish with chopped nuts, a pinch of cardamom, or a few saffron strands.

Taste adjustments (so you can fix it fast)

  • Not flavorful enough: Add a spoonful of extra paste (or a pinch more fennel/cardamom), then chill again.
  • Too thick: Add a little cold milk and stir.
  • Too sweet: Dilute with milk; add a touch more pepper or cardamom to rebalance.
  • Grainy texture: Blend longer and/or strain through finer cloth.

Popular variations

Bhang-style thandai (adult, region-specific)

Some Holi traditions include bhang. If you choose to make it, follow local laws and safety guidance, and keep it clearly labeled and away from children.

Vegan thandai

Use a creamy plant milk (oat, cashew, or almond). Cashew milk tends to give the closest richness. Sweeten to taste and chill well.

Extra aromatic thandai

Add a few drops of rose water or kewra water at the end (after blending). Start tiny—these can overpower quickly.

Make-ahead and storage

  • Make ahead: Thandai tastes better after chilling because the flavors meld.
  • Fridge: Store in a sealed bottle/jug for up to 2–3 days. Shake or stir before serving as natural settling is normal.
  • Thandai paste: You can prepare the paste in advance and refrigerate it (tightly sealed) for 2–3 days; mix into fresh milk when needed.

Quick checklist

  • Soak nuts → blend paste with spices
  • Sweeten milk (warm a portion if needed)
  • Mix + optional blend
  • Optional strain
