Hints of vanilla and cooking potatoes waft through the air inside the Sub-Zero, Wolf and Cove showroom in Columbia. Stepping into a kitchen equipment showroom like this, you don’t ordinarily expect to see an in-house chef putting the appliances to the test. But inside this space, Chef Sean Tener transforms the setting into a homelike hub for customers and his guests through his cooking.
A graduate of the former L’Academie de Cuisine in Gaithersburg, Tener began his culinary career at Bibiana, a Washingtonian Top 100 establishment. He transferred to Michelin-starred Italian restaurant Masseria, where he served as the chef de cuisine under Chef Nicholas Stefanelli. After service to Officina at The Wharf and Ability Nutrition, Tener found his way to Sub-Zero, Wolf and Cove.
On any given day, Tener may be preparing fresh biscotti or full meals in the live studio kitchen for consumers. As he does so, guests can learn about the features and functions of the appliances.
Tener’s love for fine cooking and dining is evident in dishes such as the potato gnocchi and chiffon cake with creme anglaise, both represented in the recipes he’s shared here.

Potato Gnocchi
Makes 4 servings
2 to 3 medium potatoes
2 cups all-purpose or pasta flour
1 large egg
2 teaspoons coarse salt
1 teaspoon freshly grated nutmeg

1. Preheat oven to 400 degrees. Bake potatoes in a foil-covered pan until completely cooked through, about 1 hour.
2. Peel potatoes directly into a food mill and pass them through onto a clean countertop.
3. Pour flour over the potatoes. Add egg on top of the flour. Evenly sprinkle salt and nutmeg over the flour and potatoes.
4. Using the bench scraper, chop the potato mixture back and forth to begin the mixing process. Scrape and lift the bottom of the pile over the top. Using clean hands, mold the dough until it’s fully mixed. Cover and allow the dough to rest for 15 to 20 minutes.
5. Using a bench scraper or a knife, cut the dough into strips. Roll the dough by hand into ropes of even width. Dust dough ropes with flour evenly and roll them back and forth. Cut ropes into 1-inch pieces of dough and dust them with more flour to keep them from sticking to the work surface.
6. Using your thumb, gently push down the pieces of dough with the tines of a fork to create an imprint. Dust the pieces of dough with more flour and place them on a tray in a single layer.
7. Blanch the pieces in a large saucepan of boiling water, stirring periodically to keep the gnocchi from sticking together while cooking.
8. When the gnocchi all float to the top, remove them from the saucepan and transfer to serving plates. Serve with your desired sauce or toppings.

for 15 minutes. Serve with creme anglaise (below) and fresh berries.
For the Creme Anglaise:
