What is Bostock?

If you make a lot of bread (like me), Bostock is going to be your new bestfriend.

Bostock is my absolute favorite way to use up day-old bread. Traditionally made with thick slices of brioche that are drenched in sugar syrup, layered with jam, almond paste and nuts. As it bakes the bread is refreshed and bakes up light and sweet while the exterior becomes crunchy. It basically tastes like a cross between a pillowy French toast with the flavor and crispy edges of an almond croissant.

Commonly sold at French bakeries, you can find bostock right beside croissants, pain au chocolat and mille feuille. I don't know the exact origins of this bake, but I imagine it was created as a way to prevent brioche from going to waste. It can be served for breakfast or dessert.

Formula for Bostock

Bostock can be broken down into a simple formula and is endlessly adaptable. You can go as fancy or as basic as you want. 

• Bread: Brioche is the traditional base for Bostock, so I always save a few slices so I can make it anytime I bake Sourdough Brioche. However, any soft enriched bread would work great use store bought or make your own! Sourdough Milk Bread, Sourdough Challah or even Sourdough Discard Sandwich Bread are all great options.
• Sugar syrup: A simple combination of water and sugar, makes the bread soft and sweet. Use fruit juice or wine to add more flavor to your syrup.
• Fruit spread: I love using homemade raspberry preserves, but any great-quality store-bought jam, jelly or even lemon curd would work
• Almond paste: Also known as frangipane in French, almond paste, is a pastry cream made of ground nuts (usually almonds), butter, eggs, sugar and a little bit of flour. Frangipane is easy to make at home but you can use store bought if you prefer
• Flaked almonds or fruit (optional): Adds texture and makes for a lovely topping but totally optional.

What you need

Similar to the majority of my baked goods, I tend to make all the components from scratch. If you already have some day-old bread all you need are a handful of common pantry ingredients to make this yummy French pastry.

Enriched bread: Day-old bread is best since it will absorb the sugar syrup much better. It's best not to use Crusty Sourdough Bread for this bake since it has a different structure and will change the texture of the bake.
Ground almonds: You can use almond meal or almond flour for this recipe but I find that grinding your own imparts a better flavor to the almond paste. Walnuts, pecans, cashews and pistachios are great substitutes.
Vanilla extract: Imparts flavor to the frangipane, you can also add almond extract to enhance the flavor of your almond paste. You can also substitute rum or bourbon if you have it.

See the recipe card for full ingredient amounts.

What is enriched bread?

If you've been baking sourdough bread for a while, you'll know that the basic ingredients for bread are flour, water, salt and yeast (or sourdough starter). These components create a "lean dough" which bakes up into a crusty rustic loaf.

Anything else added to the dough beyond these four basic ingredients, such as eggs, milk, oil, sugar and butter are known as enrichments. These additions usually impede gluten development which has the effect of transforming the internal structure of your bread, making the crumb tighter and softer.

Apart from the commonly used dairy, eggs, and sugar, there's a whole world of other ingredients you can use to enrich your dough. Take, for instance, pumpkin, a key component in my Pumpkin Sourdough Cinnamon Rolls, or even potatoes, which lend their magic to my Potato Sourdough Sandwich Bread. There's no limit to the creativity you can infuse into your baking!

Variations

There are so many ways to customize this bake! The possibilities are really endless.

• Make stewed fruit: Cook fresh berries, peaches or apples in your sugar syrup and pile it on the bread instead of using jam.
• Add chocolate: Layer Nutella on the bread or top with chocolate chips.
• Customize your frangipane: You can make frangipane out of any type of nut. Pistachios, hazelnuts, walnuts, and cashews are great options, or you can even use tahini.
• Use fresh fruits: A common way I like to make my Bostock is my adding fresh blueberries on top of with my flaked almonds.
• Make a cream cheese topping: Transform your Bostock into yummy cheesecake toast by using cream cheese icing or even ricotta.
• Change up the toppings: Instead of flaked almonds, use coconut flakes, pistachios, hazelnuts or even chocolate.
