Melt the 110 g Valrhona Manjari 64% Dark Couverture Chocolate Feves while also heating the oat milk, starch, and honey to 160/170°F (70/75°C). Then combine in 3 stages.
Blend with an immersion blender to perfect the emulsion.
Pour the mixture out into a rectangular container so that it sets more effectively and cover its surface with plastic wrap.
Set aside in the refrigerator, ideally for 12 hours.
Cocoa Macaron Shells
Mix and sift together the almond flour, 15 g Valrhona Cocoa Powder, and confectioners’ sugar.
Beat 35g of aquafaba in a bowl using an immersion blender fitted with a whisk attachment.
Cook the sugar and water at 230/235°F (110/112°C) and pour them into the beaten aquafaba.
Beat until cool, and add the 35g of aquafaba which you haven’t beaten.
Gently mix this with the dry ingredients using a spatula or scraper.
Use a piping bag fitted with a plain round no.8 nozzle to pipe the macarons onto parchment paper.
Bake at 300°F (150°C) in a fan-assisted oven for 16 minutes.
Assembly and Finishing
Turn the cooked and cooled macarons over, fill them with ganache using a piping bag with a 12mm plain round nozzle, and stick the shells together. You can store your macarons in the freezer.
Notes
Prepare a day in advance : Manjari 64% plant-based ganacheMake on the day : Cocoa macaron shellsChef's tip : The French language has a special word to describe how to mix macarons. The verb “macaronner” means to combine ingredients together gently using a spatula or scraper until the mixture is smooth and shiny and doesn’t have any air bubbles.
Nutritional advice : Because it forms a light, airy mousse, chickpea juice, also known as aquafaba, is an ideal substitute for egg whites in macaron recipes for vegans and anyone who wants to avoid eggs.
