Hollandaise sauce (pron.: /hɒlənˈdeɪz/ or /ˈhɒləndeɪz/; French: [ʔɔ.lɑ̃.dɛz]) is a mixture of egg yolk and butter, usually seasoned with lemon juice, salt, and a little white pepper or cayenne pepper. In appearance, it is light yellow and opaque, smooth and creamy. The flavor is rich and buttery, with a mild tang added by an acidic component such as lemon juice, yet not so strong as to overpower mildly-flavored foods.
