Sweet Collaborations from the Chocolate Lab and Hydroponic Farm at ICE

Every time I walk past the brightly lit farm, I can almost taste the dozens of flavors growing within and my imagination immediately starts to stir. This first in a series of posts traces some inspired ideas that emerge when we crossbreed these amazing raw materials with advanced pastry projects in the Chocolate Lab.

The farm features several staple herbs — varieties of basils and mints, for example — plus new and exciting crops rotating into production on a weekly basis. During a recent tour and tasting of the hydroponic farm’s offerings, two items stood out: anise hyssop and purple oxalis. The former was an old friend, a sweet expression of licorice and mint.

The latter, however, was something I was unfamiliar with. A relative of the sorrel family, the deep violet leaves of the oxalis resemble the flapping wings of a butterfly and provide an interesting tartness. More surprising was the flavor that came from its stem — a refreshing acidity that called to mind delicate young rhubarb stalks. To highlight these herbs, I began constructing flavors and textures in my mind. Sweet apricot, aromatic vanilla, honey, cream…with these building blocks in place, I picked my hyssop and oxalis and then headed into the lab.

As I assembled ingredients, the dessert’s architecture materialized. The anise hyssop would infuse an airy mousse, or parfait. The apricot would be lightly sweetened with honey and provide a fluid liquid center inside the parfait. A shiny glaze speckled with vanilla would enrobe the parfait, which would find its place atop a crunchy, buttery pastry base.

Still enamored with the oxalis stems, I considered lightly candying them to preserve their slender form and to balance their flavor. The format of a petit gateau, an individual dessert often found in boutique pastry shops, offered the perfect format in which to condense these flavors and textures for maximum impact.

Stay tuned for more sweet collaborations with the hydroponic farm at ICE!

3. Add the remaining flour (2); process just until incorporated – take care not to overmix. Wrap the dough and chill.
4. Chill or freeze. Allow a minimum of one hour resting period before use. Roll or sheet very thin, to a half sheet pan sized rectangle. Transfer to mesh silicone mat and par-bake sheets for five minutes at 150°C/300°F to set; cut 7cm (2 ¾ in.) discs and continue baking approximately five to ten minutes, or until golden brown.

Honey Apricot Coulant

• 0.5 sheet gelatin, hydrated
• 200g apricot puree
• 15g honey

1. Place the milk and anise hyssop in a small saucepan and bring to a simmer over low heat, remove from heat, cover and allow the mixture to infuse for 20 minutes. Strain.
2. Prepare a crème anglaise with the infused milk, egg yolk and sucrose; cook to 84°C/183° Add the hydrated gelatin. Strain and cool to 25°C/77°F.
3. Fold the crème anglaise base into the whipped cream and deposit into silicone ‘stone’ molds. Allow to stand at room temperature for five to ten minutes, insert the frozen apricot coulant centers, top off the mold with additional mousse if necessary and continue to freeze completely.

Glaçage
