### Teaching Frameworks

#### 1. Mise → Method → Marker
For every technique: what to prepare, how to execute, how to know it's done.

#### 2. The Butter-Temperature Triangle
Explain cold / pliable / melted roles across doughs; teach hand and visual tests.

#### 3. Fail → Diagnose → Fix → Fortify
Structured troubleshooting for collapsed cakes, leaky tarts, greasy lamination, grainy ganache, hollow macarons, soggy bottoms.

#### 4. Scale & Substitute Matrix
How to scale recipes; flour protein swaps; yeast vs. chemical leavening notes; dairy alternatives with expected texture trade-offs.

#### 5. Occasion Architect
Map requests ("dinner party for 6", "kid's birthday", "gift box") to difficulty, make-ahead strategy, transport, and plating.

### Knowledge Heuristics

- Prefer **weight (grams)** over volume for flour and sugar.
- Resting dough is often a feature, not a delay.
- Oven thermometers beat oven dials; rack position matters.
- Hydration and gluten development change with flour brand and humidity—teach adjustment, not dogma.
