Molecular Gastronomy – Transformation walnut dust biscuits

By Chef Tali Clavijo

so today I felt like making something sweet and powdery. I’m just fascinated by fine powders and what better powder than tapioca maltodextrin? The ability for ‘malto’ to transform oils into powders is like a super power that only heroes are granted access too. Maybe someday I too will be able to turn fat into a fine powder…until then I will be making food that is amazing.

So, for this recipe I needed about 60 g of ‘Malto’ (tapioca maltodextrin), 145 g of walnut oil, 2.3 g of salt, and about 40 g of walnuts (I smoked mine in sugar, but you could use raw walnuts for this too).

I started by pan steaming my walnuts with some sugar for about 10 min on medium. Then I placed them aside.

Next, I measured out 60 g of ‘malto’ and added the walnut oil to the mix. I then added the salt to this mix and used a spatula to mix until the mass was even

Next, I combined the pan steamed walnuts (I did crush the walnuts to make them powdery) to the malto walnut oil and salt mixture.

I mixed until the mixture was even. Next, I spread the mixture to a thickness of 1 cm.

this process requires you to get two even leveled surfaces (about 1cm in height). Next, I covered the mixture with parchment paper and used my rolling pin to smooth out the surface of the walnut dust biscuit.

Once I rolled it enough I got a beautiful walnut dust biscuit.

Next, I cut with a circular pasta cutter

You could also just use a knife to cut shapes on the biscuit.

    again, where is the comment on the taste? whats the amazing part of your recipe? Doesn’t the walnut cookie become a goopy mess in the mouth with all of that tapioca maltodextrin? Walnut oil is pretty heavy, does the cookie have a warm taste to it even i when it is cold?

    The biscuit is not goopy. The Malto and the oil bond to form an amazing texture once introduced to your mouth it pretty much transforms and melts to a smooth well balanced texture. Moreover, the aromas are released in a manner that is not achievable through regular ingestion of the walnut oil, or walnut by itself.

    Tali,

    Great post again! I’m having serious issues getting any flavour out of my malto dusts. Any kind of oil-malto combination either become clumpy or has no flavour (due to adding more malto to try and get the desired dust effect) any advice?
