Lemon Mousse Cake

Lemon Mousse Cake

A few weeks ago I invited some friends to come over and celebrate the 3 things I love most, spring, food, and of course butter. As some of you may know, this is the second year that I am a brand ambassador for Plugrá European Style Butter. Even before becoming part of their Butter Brigade, it was my butter of choice. With the vast amount of time I spend in the kitchen, I want my edibles to be mouthwateringly delicious. A huge component of that is good quality ingredients! Plugrá Butter uses a slow-churned process that creates less moisture content and a creamier texture when compared to average table butters.This secret becomes yours for flakier pastries, unbelievably creamy sauces, rich enviable risottos, sizzling sautés, and extraordinary flavored butters.

Apart of my ambassadorship is to host a dinner party and create a menu that showcases the creamy butter. Last year, I hosted a party and used a chef inspired menu from the Plugrá Butter website. This year however I had a wonderful time creating my own butter filled menu!

I could not have been more lucky as far as weather. It was the first day of spring and absolutely beautiful out. I set my table with pretty pink linens and vintage Italian glasses. This dinner party finally gave me an excuse to buy the gorgeous gold flat wear that I had been eyeing on Ebay for the last year!  Living in Southern California and close to the water, I felt that it was my civic duty to have a surf and turf type meal but I wanted to do it with a french flair.

The appetizers consisted of fresh baked bread and a compound orange butter along with charcuterie and an array of french cheeses. The next course was a butter lettuce salad with large scallops fried in brown butter. The main course was a grilled ribeye steak garnished with a slab of Cafe de Paris. Cafe de Paris is a compound butter that has such a depth of flavor that it deserves its own post just to explain (coming tomorrow). I served the steaks with mashed potatoes and asparagus with a hollandaise sauce.

We ended the meal with this Lemon Mousse cake. Considering everyone cleaned their plates and left with a very full stomach, I will say that it was a success! I get so much joy from enjoying good food and wine with good friends!

  24. *You can also just use an extra layer of mousse to top the cake instead of whipping cream.

    Wow, thank you for sharing this amazing recipe! I too happen to like Plugra butter, my only concern with their brand is that a lot of my customers are requesting organic butter and unfortunately at this time their butter in none organic.
