Aerated Sous Vide Hollandaise
A twist on the traditional Hollandaise sauce perfectly cooked sous vide at 65 °C (149 °F) and aerated with an iSi Whip. The result is an extraordinary light Hollandaise sauce with an extra kick from the white wine vinegar that brightens the flavor.
When preparing Hollandaise sauce, temperature control is crucial. Too much heat and the yolks will curdle or the emulsion will break. Too little heat and the emulsion will fail to form. Controlling the cooking temperature with sous vide makes it foolproof and easy to obtain consistent results every time. Hollandaise sauce pairs perfectly with eggs, asparagus, potatoes, steak, fish, lobster, crab and many other foods!
