"I tried to put my original touch on these. I tried a lot of different recipes and methods to bring out the flavors," Euan says. "It takes a long time to make truffles - two days to make one batch, and everything has to be perfect."
Euan's most popular truffle, caramel, takes nine hours just to cook the caramel, which must be cooled at room temperature. If the conditions are too hot, too cold or too humid, the consistency is ruined.
One bite, and you understand why this consistency is so important. Under a sprinkling of cocoa powder and a delicate jacket of Cacao Barry dark chocolate, the caramel is so intensely creamy and soft, so rich and smooth, you wonder if you've ever really tasted caramel before.
Other marvelous flavors include strawberry (made with a fruity ganache infused with strawberry liqueur), espresso, blackberry, cognac, citron lemon, coconut and the subtly smoky Earl Grey. Like XOX, Five Star also offers a few vegan choices, including soy orange and dark chocolate.
As for the other half of the menu, the coffee, it's fresh-roasted Graffeo, which Euan brews with as much care as he crafts his truffles. He also makes a truly sublime cup of cocoa - heavy on the chocolate and with steamed milk - that has developed a following all its own.
Euan hopes to expand his business soon with a Web site and the addition of Mitchell's ice cream. In the meantime, he can be found behind the counter greeting customers, rolling chocolates, pouring good, strong coffee - and upholding my belief system.
