Method
Pan de Cristal (bread)
- 1
Autolyse and mix
In a large bowl combine 500 g bread flour and 400 g water. Mix until all flour is hydrated and a shaggy dough forms. Let autolyse 30 minutes at room temperature (this improves extensibility).
- 2
Add yeast and salt
Sprinkle 2 tsp instant yeast over the dough, then add 12 g fine sea salt. Mix gently by folding and pinching until ingredients are incorporated (about 2–3 minutes). The dough will be wet and sticky — that's normal.
- 3
Bulk fermentation with folds
Cover bowl with plastic or a damp towel and ferment at room temperature (21–24°C / 70–75°F) for 2 hours. Every 30 minutes for the first 90 minutes perform a set of stretch-and-folds: reach under one side of dough, stretch upward and fold over; rotate bowl and repeat 4–6 times. After last fold let rest until bulk ferment completes (dough should increase ~30–50% and be airy).
- 4
Pre-shape and bench rest
Lightly oil a work surface and your hands. Turn the dough onto the oiled surface, being gentle to retain gas. Divide into two equal pieces (~450–500 g each). Very gently pre-shape each piece into a loose rectangle by folding edges toward center once; do not degas. Cover and rest 20 minutes.
- 5
Final shaping into thin loaves
On a well-oiled surface, very gently stretch each piece into a thin rectangle about 25–30 cm long and 12–15 cm wide. The goal is to maintain as many air pockets as possible — handle minimally. Place each rectangle seam-side down on a well-oiled baking sheet (or couche) leaving at least 4 cm between loaves. Cover loosely and proof 45–60 minutes until slightly puffy.
- 6
Bake
Preheat oven to 250°C (480°F) with a baking stone or inverted sheet and a steam tray if available. Just before baking, drizzle 1 tsp olive oil lightly over each loaf and sprinkle lightly with flour if desired. Slide the oiled parchment (or well-oiled sheet) with loaves onto the hot stone/sheet. Inject steam (pour 250 ml hot water into steam tray or use spray) and immediately reduce temperature to 230°C (450°F). Bake 12–16 minutes until crust is deeply golden and extremely blistered/crisp. Rotate halfway if necessary. Internal temperature should be ~96°C (205°F).

Cool
Remove loaves to a wire rack and cool completely (at least 1 hour) so crumb sets and moisture redistributes. Pan de cristal is best served the same day for maximum crispness.
Lactic Strawberry Jam

Reduce to jam consistency
Maintain a gentle simmer for 12–20 minutes, stirring and pressing berries against the side of the pan with a spoon to break them down to your preferred texture. The lactic whey will add a mild tang and help preserve a fresh flavor. To test, place a small spoonful on a chilled plate — it should wrinkle when pushed after cooling for 15–30 seconds. Remove from heat.

Cool and store
Let jam cool slightly, then transfer to a sterilized jar. Cool to room temperature, then refrigerate. Jam will thicken as it cools. Keeps 2–3 weeks refrigerated.
Cultured Butter
- 12
Culturing the cream
Pour 500 ml heavy cream into a clean jar. Stir in 2 tsp buttermilk or live-culture yogurt to inoculate. Cover loosely and leave at warm room temperature (20–25°C / 68–77°F) for 12–18 hours until the cream smells pleasantly tangy and slightly thickened.
- 13
Chill and churn
After culturing, chill the cream for 1–2 hours until cold (this helps the butterfat coalesce). Using a stand mixer with whisk or a jar/shaking method, whip/churn the cultured cream on medium-high. First it will become whipped cream, then collapse into a grainy curd and buttermilk will separate. This can take 5–15 minutes depending on method.
- 14
Wash and knead
Pour off and reserve the buttermilk. Place the butter solids in a bowl and wash with cold water, kneading gently to remove remaining buttermilk (repeat 2–3 times) until the water runs clear. This helps shelf life. Season with up to 2 tsp fine sea salt if desired and knead to distribute.
- 15
Shape and store
Form butter into a log or block, wrap in parchment, and refrigerate. Keep refrigerated and use within 1–2 weeks. Reserved buttermilk can be used in baking.
