Filter Coffee — Chicory Ratio and Tumbler Decoction (ഫില്‍ടര്‍ കോഫി)

Ingredients

• For the decoction
• 28 g South Indian filter coffee-chicory blend (70–80% coffee, 20–30% chicory), coarse grind; Cothas, Leo Coffee, or Narasu's are the reference brands
• 200 ml water, heated to 92–94 °C; not a full boil
• For the tumbler
• 300 ml full-fat cow's milk, brought to a full boil then kept hot
• 2 tsp white sugar, or to taste

Method

1. 1
   Bring 200 ml water to 92–94 °C — a vigorous steam without a rolling boil — because water at a full boil scorches the chicory and drives off the aromatic top notes that make the decoction smell alive in the cup. Meanwhile, bring the full-fat milk to a full boil in a separate vessel and hold it hot.
2. 2
   Place the upper chamber of the metal two-part filter over the lower collecting vessel. Add the coffee-chicory powder and press it firmly but without excessive force into an even, compact cake, so the water must travel slowly through the entire bed rather than finding a fast channel at the edge. A cake that yields only slightly to a gentle fingertip press is correct; a loose pack drains too fast and under-extracts.
3. 3
   Pour the measured hot water evenly over the packed cake in a steady, circular motion so no dry pocket escapes wetting. Set the lid on the filter and allow the decoction to drip through for 15–20 minutes undisturbed — this is where the dish lives or dies, because the slow drip is the sole extraction; pouring additional water or disturbing the cake cuts short what the chicory root and coffee can give, and no subsequent step can restore the lost body.
4. 4
   When dripping has ceased, lift the upper chamber away cleanly so no spent grounds fall into the collect. The decoction in the lower chamber should be a deep, near-opaque mahogany-brown; approximately 80–100 ml of concentrated liquid is correct for two servings.
5. 5
   Divide the hot boiled milk between the two dabarah-tumbler sets, roughly 150 ml per tumbler, pouring it while it is still at or near the boil so the decoction does not chill on contact and turn flat. Add the sugar, then pour the decoction into each tumbler at a ratio of 1 part decoction to 3–5 parts milk, adjusting to strength preference.
6. 6
   Pour the coffee from the tumbler into the dabarah from a height of 20–30 cm, then back into the tumbler, and repeat 4–5 times in total, so the falling stream folds air into the liquid and builds the dense, pale-tan foam that is the mark of a properly made tumbler coffee. Absence of foam tells you the pour height was insufficient or the milk had already lost too much heat before you began.
7. 7
   Serve immediately in the tumbler, set inside the dabarah, and drink directly from the dabarah lip. The foam should hold for the first several sips — bittersweet, with the chicory's earthy depth and the milk's roundness meeting in even balance.
