A Thai tea canelé scaled to fill a 24-mold tray, with evaporated milk at ~36% of the dairy for the cooked-milk body that reads as authentic cha yen. A custardy Canelé sized for the full tray.

Ingredients

   
638g milk (for steeping)
62g Thai tea mix (ChaTraMue “Number One” brand)
352g evaporated milk
84g heavy cream
99g butter
2 vanilla beans (or 16g vanilla extract)
341g granulated sugar
4g fleur de sel
2 whole eggs (~110g)
5 egg yolks (~90g)
187g AP flour
33g cornstarch
  Nonstick spray for molds
  Optional: a drizzle of sweetened condensed milk on the unmolded canelés

Steps

  1. Heat the 638g milk to 175°F — do not boil. Off heat, add the Thai tea mix, cover, and steep 12–15 minutes. Steep strong — the flavor mutes sharply over a 60-minute bake.

  2. Strain through a fine sieve lined with cheesecloth or a cloth tea filter (the mix is dust-fine; pass it 2–3 times for a clean, deep-orange liquid). Weigh the strained milk and measure out 550g — top up with fresh milk if short. Return the 550g to the pot with the evaporated milk, cream, butter, and vanilla and warm gently to melt the butter.

  3. In a bowl, whisk sugar, salt, eggs, and yolks together.

  4. Slowly pour about ¼ of the warm dairy into the egg mixture, whisking to temper. Sift in flour and cornstarch, whisk until smooth.

  5. Gradually add the remaining dairy, whisking until smooth.

  6. Strain through a sieve. Refrigerate overnight (24 hours minimum).

  7. Coat 24 molds with nonstick spray. Stir rested batter gently. Preheat oven to 525°F (550°F for a full tray with no steel — see Big-Batch Canelé). Fill each mold with ~75g.

  8. Bake at 525°F for 11 minutes, then drop to 400°F for 50–55 minutes. Evaporated-forward batter + a full tray both brown unevenly — favor heat over time, watch the last ~10 min, pull at deep mahogany. (If shells darken too fast, drop the second stage to 375°F.)

  9. Unmold immediately onto a cooling rack. Cool 2 hours. Eat the same day.

Analysis

Total batter weight: ~1835g (after straining the tea; excludes mold coating)

Component Amount %
Structure solids (flour + cornstarch) 220g 12.0%
Fat (butter, cream, evaporated milk, milk, yolk) 189g 10.3%
Sugar (added + lactose) 407g 22.2%
Liquid (milk, cream, evaporated milk, egg water) 964g 52.5%
Egg/milk protein 62g 3.4%

The evaporated-forward single batch at 2.2× the volume — structure ~12% (custardy), fat ~10.3% (cream + heavy evaporated), sugar trimmed for the evaporated lactose. Modeled on the verified HK Milk Tea decomposition; only the oven’s heat recovery changes at full-tray scale.

Notes

  • Evaporated milk is ~36% of the dairy (352g of ~974g) — the lever that makes the cooked-milk note actually read, rather than just sitting on the label. See Evaporated Milk and Condensed Milk for the swap science.
  • Steep into plain milk, add the evaporated after — set tea strength against the milk only, measure back to 550g, then add the 352g evaporated. Don’t steep into the evaporated milk (scorches; can’t measure-back cleanly).
  • Full-tray oven handling (steel, preheat, no door-opening, bake-12 fallback) is in Big-Batch Canelé and applies here.
  • Sugar trimmed to 341g to offset the evaporated lactose; the traditional cha-yen sweetness is meant to come from a condensed-milk drizzle on top — add it on the unmolded canelés for the full effect.
  • Use real ChaTraMue mix (the orange “Number One” bag) — the malty body, vanilla note, and orange all come from the blend.
  • Milk starts at 638g (vs the 550g measure-back) to cover what the mix soaks up.

Experiment note

This pushes evaporated milk hard (~36% of the dairy) for a creamy, authentic cha-yen body. To compare on a real tray, bake it alongside the Big-Batch Hong Kong Milk Tea Canelé, which uses evaporated milk more lightly. For a condensed-milk arm, add ~175g sweetened condensed milk and cut granulated sugar by ~95g (the ~0.55g-sugar-per-gram rule from the Condensed Milk article) — expect a softer, gooier set, so bump cornstarch to ~40g and bake a touch cooler.
