Walnut oil ? 
Hot or cold?
The kernel consists of water and oil. When roasting the kernels, the water evaporates and the oil begins to show up. The taste of the nut will be more pronounced because it is by roasting that the flavors come out! It takes 2kg of kernels to make 1L of oil.
Cold-pressed walnut oil, on the other hand, will keep the water from the kernel, which does not mix well with the oil and which will make it rancid faster. In addition, its taste will be less interesting, as will its profitability (2kg of kernels per 75cL of oil).
What can you accommodate it with?
Walnut oil is mainly used cold, for salads of course, but also for many other dishes. It will go with a Rocamadour cheese, a beef carpaccio or even a velvety nettle!
It is possible to incorporate it into a pie dough or cake, in the oven at 180°C or to place a fillet at the end of cooking.
How to keep it?
High-quality, hot-pressed walnut oil keeps for a long time, contrary to what is often heard. For our oils, you can count on:
– Before opening: 2 years in the closet, out of the sun.
– After opening: 1 year minimum, either in the refrigerator or in the cupboard, protected from humidity and temperature changes.
Manufacture of walnut oil
First, we separate the kernels from their shells, either manually or mechanically, but carefully sorted. Then, the oil maker places them under the 800kg granite grinder, which will crush them for half an hour until a paste resembling a cookie dough is obtained.
Finally, the walnut paste will be placed in the hydraulic press to extract its oil. In the press, we get the nutcake. It is the kernel emptied of its oil. We sift it into walnut powder.
We place the oil in stainless steel tanks to let it settle for 3 weeks before bottling it in the shop.
