Earlier this month, I attended an event called “A Sweet Taste of Destination Kohler” at The Social Table here in Chicago (super cute venue btw!)

You may remember my trip to the Kohler Food and Wine Experience last fall – I felt like this was a mini taste of all of that awesomeness brought right to my door.

A few Chicago bloggers and myself got to experience an intimate and interactive evening with Destination Kohler’s award-winning Executive Pastry Chef, Josh Johnson and Head Chocolatier, Anette Righi DeFendi.

I had a great time! I ate a lot of chocolate (and drank a little wine.)

We got to help Chef Josh make this delicious dessert; I originally intended to share one of his recipes here with you but I had trouble getting one of the components.

If I can’t find it, you probably can’t either so I created a cupcake “inspired” by what we ate (more on that in a little bit.)

After that Chocolatier Anette led us through three chocolate pairings. I loved her choices! I even wrote down the names of all of the beverages she chose so I can add them to my boozy repertoire.

The tawny port she chose was a particular favorite of mine (and it’s already on my shopping list!)

If you want to partake in some of the awesome chocolates of Kohler, consider attending In Celebration of Chocolate this weekend. The three-day cocoa-centric soiree will see notable Chicago-based Executive Pastry Chef, Toni Roberts (theWit Hotel, Chicago) and Donald Wressell, Executive Pastry Chef at the renowned Guittard Chocolate Company, along with Josh and Anette.

Demonstrations include putting together a dark chocolate s’mores parfait, DIY chocolate sculptures and a hands-on experience discovering the secrets of chocolate with Anette.

Or you can order some Kohler chocolates from their website, like Dark Chocolate Hearts or my favorite, the Buttery Terrapins.

Chocolate Cupcakes with Grapefruit Curd and Grapefruit Buttercream Frosting

Since I couldn’t replicate Josh’s recipes, I made some cupcakes. Nothing like dealing with frustration with a delicious sweet treat.

These chocolate cupcakes are moist and delicious. I followed a chocolate cake recipe on King Arthur’s Flour exactly, so I’m not going to rewrite it here.

Head over there and it will make 24 cupcakes.

The piece de resistance of this post is the grapefruit curd and the grapefruit buttercream frosting. I just couldn’t resist the flavors – grapefruit is quickly becoming my new favorite citrus.

When you decide to make these cupcakes, make the grapefruit curd first. While it’s cooling/setting, make your cupcakes. Since you should wait to frost the cupcakes until they are cooled, go watch a movie or go for a walk.

When you come back, whip up the grapefruit buttercream frosting.

To assemble the cupcakes, use a butter knife to remove the center of the cooled cupcakes. Use a spoon to fill the cavity with grapefruit curd.

When frosting, pipe frosting over the grapefruit curd and then pipe frosting around that. This will help stop the curd from jumping ship.

I made the buttercream and curd recipes for some cupcakes last month. Unfortunately, I ran out of time and had to skip filling the lemon cupcakes with the curd (which I made the day after the event at which the cupcakes were served).

In any case, the buttercream was great and the curd even better (if a bit more liquid than I would have liked but I wonder if that was me - there was no way that it was going to cook for 15 minutes without boiling - by five it was already thickened and threatening to boil).

In any case, you write, "We got to help Chef Josh make this delicious dessert; I originally intended to share one of his recipes here with you but I had trouble getting one of the components." Out of curiosity, what was this dessert whose ingredient you couldn't find and whose recipe you didn't share?

Hi Steven, thanks for your comment! The recipe this was inspired by belonged to the chocolatier of Kohler's American Club resort. It included a variety of food-grade products that I wasn't able to source but I am happy with the results of these cupcakes. Glad you were too!
