Preservative oil, an asset for taste

When you prepare a dish using an ingredient that has been preserved in fat, for example a springtime mixed salad with tuna in oil or sun-dried tomatoes, you're probably going to make a french dressing (vinaigrette) next.

In that case, why not use the preserved oil from the tuna or tomatoes?

Preservative oil, an asset for taste

It's not easy, or rather it's not something you think about very much, but it's a shame to throw away the oil used to preserve tuna or tomatoes, because it's naturally perfumed with whatever's been preserved in it.
And this taste, these aromas, will then be transmitted to your future preparations.

To take the example of the tuna in oil and the vinaigrette sauce for the salad, you proceed as usual for your salad, but when you add the tuna you collect the oil in a bowl or small jar.
Add vinegar, mustard, salt and pepper, mix well and your tuna-flavoured dressing is ready.

Just about anything that can be preserved in oil (fish, vegetables, cheese, etc.) can be used in this way, not just in a sauce, but as a cooking fat, for example.
Grill tomatoes in a little rosemary oil with cubes of feta cheese, for example, and you'll be amazed at the results.

So far, we've only talked about oil, but this applies to virtually all preservative fats.
In the same spirit, another example: roast potatoes in a little rillettes fat, and enjoy the resulting taste, in addition to the crispness of the roasted potatoes.

To sum up: don't necessarily throw away the fat used to preserve your food - it can often be used to accompany a recipe, or in cooking.

The strange foam of potatoes in milk

As you may have already noticed, when you cook potatoes in milk, especially in small pieces (slices or cubes) for a gratin for example, a surprisingly abundant white foam forms on the surface. Where does it come from?

A little leftover butter

Very often when you're making a cake, your recipe will tell you to melt some butter and mix it into the batter - a classic for cookies, cakes, moelleux and the like. And every time you do this, you'll have to butter the baking tin to prevent the dough from sticking during baking. Naturally,...

A tablet holder

Pre-calibrated pastry dough

When making pie dough (shortbread, shortcrust, sweet...), it's always a good idea to make a lot at once, and then divide it into pieces, which you can freeze. I've already pointed out the mistake not to make, which is to form a ball before freezing. It's difficult to roll out afterwards because...

Butter vs. grease

We often read in a recipe where a pastry is put into a mould that, just before pouring, the mould should be buttered or greased. But what's the difference between these 2 terms?

The secret of cooking until "done"

This is a real chef's skill: being able to look at a fish fillet cooking and say, "Stop – that's enough, it's cooked". I always admire this ability to see at a glance if something is done. It is what sets the professionals apart from us mere amateurs. And it's true that how fish is cooked is...

The window-pane test in bread-making

The home bread-makers often ask themselves “Have I kneaded my dough long enough?” . A good question, as dough that is insufficiently kneaded will not rise properly or will fall flat when the top is slashed, which is very frustrating. To know when the dough is ready, one can rely on the length...
