with regards to the chantilly of herve this if i am not mistaken, in all of the recipes i have used, the fat had to be heated. for example chocolate or cheese melted into milk; the gagnaire/this references include melted butter into liquid, then whipped; i believe it was a kientzheim instead of mayonnaise. i dont remember any of these made with oils that are liquid at room temperature, do you? for this i just know the false pil pil which is oil trapped in a water/agar base. but it doesnt whip like cream, it resembles more of an egg white mayonnaise any thoughts?
