Crystal bread is a Spanish bread known for its paper-thin crust and very open, airy crumb. Its name refers to the light, crisp texture created by a dough made with a high proportion of water.
No. Crystal bread typically has a wetter dough, a thinner crisp crust, and larger, more irregular air pockets than ciabatta. Both are airy wheat breads, but their textures and traditional methods are not identical.
Crystal bread dough is deliberately very wet to create its distinctive open crumb. Instead of adding lots of extra flour, handle it with wet hands and use folds during resting to build structure without making the loaf dense.
Crystal bread is often split and topped with ripe tomato and olive oil, in the Catalan style known as pa amb tomàquet. Its crisp surface and airy interior also make it a good base for cheese, cured meats, or sandwiches.
The large holes in crystal bread form as gas expands inside its highly hydrated dough during baking. Gentle handling matters: pressing or overworking the dough can push out the bubbles that give the bread its open texture.
Yes, you can make crystal bread at home, though the sticky dough takes patience. Let it rest and strengthen it with repeated folds, then shape it gently and bake in a thoroughly preheated oven.
Bread flour is a reliable choice for crystal bread because its stronger gluten helps hold the wet dough and its air pockets. Flour strength varies, so follow a tested recipe rather than adding flour until the dough feels dry.
Crystal bread is best eaten on the day it is baked, when its thin crust is crisp. Keep leftovers in a paper bag at room temperature for short-term storage; an airtight plastic bag can soften the crust.
Yes, crystal bread freezes well. Cool it completely, slice it, and seal the slices in a freezer-safe bag. Reheat frozen slices in an oven or toaster to bring back some of the crisp crust.
Yes, crystal bread works well for sandwiches, especially with moist fillings such as tomato, roasted vegetables, or fresh cheese. Its open crumb absorbs flavorful juices, while cutting it horizontally makes the thin, crisp loaf easier to fill.

Crystal bread, known in Spain as pan de cristal, is a high-hydration loaf associated with Catalonia. Its very thin, crisp crust surrounds a light crumb with large, irregular air pockets. The name refers to its delicate, almost translucent structure rather than to any added ingredient.
In Spain, it is often sliced and served with olive oil, tomatoes or cured meats, and its open texture also makes it a good base for sandwiches. Elsewhere, try it alongside soup or with a simple savoury topping. It is mainly a source of carbohydrate and is relatively low in fat; a 30 g slice provides a modest portion. Add vegetables and a protein-rich topping for a more filling meal.
Low
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
