A wooden spoon allows the cook to draw their finger through the sauce on the back of the spoon. If the line stays, the sauce is thickened and done.
no there is a different reason. you can check for nappe on a rubber spatula also, however in a french kitchen you are to use only a wooden spoon. I believe it has something to do with how the eggs cook.
Which is why Julia Child did her books about french cooking--and stayed with the important things instead of the trivial things.
Making it accessible to home cooks and breaking down the BS for home cooks.
no, there is a scientific reason. harold mcgee has talked about it in the past, but i cannot remember what his conclusion was.
also, i love julia child, but she was wrong about a lot of stuff
The classic French sauce stirring technique is the "figure eight" which you can do with a wooden spoon but not with a whisk. Let's just say it works and leave it at that.
Really? I do the "figure eight" with a whisk just fine.
A whisk will incorporate air. making little air bubbles and a wooden spoon doesn't do that. That is what my first pastry chef always told me, especially when making creme brulee.
Isnt't it something about the sound the sauce makes? I personally find that if you listen to it, it "tells" you when the custard is reaching the thickening point and helps you take it off the heat at the right time. Technically a whisk doesn't give a good feel for the resistance of the moving fluid as it changes,which is basically another indicator for the above. And the spatula will create additinal slosh because of the flexibility of the silicone. I'd love to know what Mr McGee said, if somebody recalls.
You don't want metal to react with egg.
The whisk generates air and incorporates it into the sauce, whereas the wooden spoon does not. Use a wooden spoon for creme anglais, a whisk for sabayon.
Personally, I think a silicone spoonula is even better because it scrapes the bottom of the pan more evenly, and you can check for nappe on the back. I worked for a french chef who insisted on wood; I think it was a habit thing. I converted him to the spoonula, but it took months!
I use either a flat-bottomed wooden spatula or one of silicone or rubber. As spiffypaws points out, any of them makes continuous contact with the bottom of the pot, whatever stirring motion you choose to use. I cook crème anglaise in a bain marie to 165 degrees.
