A good Hollandaise sauce does it for me. And I hadn't found one at a restaurant here in the Denver metro area until today.
We had brunch at The Delectable Egg in Westminster this morning. I finally got brave enough to try their Hollandaise sauce - I was starting to think that Denver had a different definition of Hollandaise than the rest of the world, cause everywhere I'd had it it was sour or clumpy or way too runny, so I've been avoiding ordering anything with Hollandaise sauce unless I really trusted the kitchen, and even then it was bad (shame on you, Racine's!). This Hollandaise was divine - every mouthful had me closing my eyes to savor it. I could have eaten two plates of Quiche Lorraine crepes, it was so good.
