Slice the fruit if necessary and divide it among four individual shallow serving bowls. Find a medium (4-quart) saucepan and a stainless steel bowl that will nestle at least halfway into it. Fill the saucepan with 1 inch of water and set it over medium-high heat.
In the stainless steel bowl, whisk together the egg yolks, sugar, juices, tequila and lime zest.
Nestle the bowl into the saucepan (the water should be boiling now—if it’s not, wait until it is) and lower the heat so that the water is at a low simmer—somewhere between medium and medium-low. Whisk the yolk mixture continuously, until it becomes thick and fluffy, about 3 minutes. Remove the bowl from the saucepan. Drape a few spoonfuls of the warm “espuma” over each bowl of fruit and serve immediately with something crunchy and sweet—either on the side or crumbled on top.
Riff: Cool espuma
The warm espuma from the recipe above needs to be served right away or it deflates into an unappetizing consistency. So the French make a cool version they called sabayon by allowing the beaten cooked mixture to cool just to room temperature and folding in whipped cream. Beat ½ cup heavy cream to soft peaks and fold it into the room temperature espuma. Cover it, stick it in the fridge and spoon over fruit when you’re ready (it will keep for a day or so).
Thank you s much for all your hard work and dedication to the Mexican foods. I hope sometime to visit your restaurant and taste for myself in the meantime the cook books and recipes have been great
Thank you for sharing your incredible love of this cuisine. Your explanations and instructions make it easy to prepare and give us a deeper understanding. Your restaurants have spoiled us for any other Mexican food so we try to make the 3 hr drive there as often as possible! Thank you!
