Thai Tea Oreo® Ice Cream

Heat heavy cream, 1 cup half-and-half, and milk in a saucepan over medium heat until it begins to simmer, about 10 minutes; stir in Thai tea mix and bring to a boil. Reduce heat to low; simmer 5 minutes, or up to 10 minutes for more tea flavor.

Whisk about 1/4 cup cream mixture, a teaspoon at a time, into beaten egg; whisk beaten egg mixture into cream mixture in saucepan and cook until slightly thickened, about 1 minute. Strain cream mixture through a cheesecloth-lined sieve; discard tea leaves.

Beat remaining 1 cup half-and-half, sweetened condensed milk, and vanilla extract into cream mixture until well blended; cover and chill for at least 6 hours or overnight.

Freeze cream mixture in ice cream maker according to manufacturer's instructions. When ice cream is semi-solid, churn in 3/4 of the crushed chocolate sandwich cookies; continue to churn until ice cream is desired consistency, then fold in remaining cookies. Serve immediately or freeze for several hours for a harder ice cream.
