Beurre Monté

• ½ cup (120 ml) heavy cream
• 1 sprig thyme

In a heavy-bottomed pot over medium-high heat, bring the heavy cream with the sprig of thyme to a simmer.

Whisk the cornstarch and 1½ tablespoons water together to make a slurry and stir it into the heavy cream. Once the cream has thickened, remove the thyme sprig and discard.
