Combine milk and cream in a saucepan and warm over low heat until foam forms around the edges. Remove from heat.

Combine egg yolks, sugar, scraped vanilla bean seeds, and chestnut flour in a large bowl and beat with an electric mixer until frothy. Gradually pour warm milk into egg yolk mixture, whisking constantly.

3 . Stage

Return mixture to saucepan; add scraped vanilla bean and cook over medium heat, stirring with a wooden spoon until the mixture gels slightly and coats the back of the spoon. If small egg lumps begin to show, remove from heat immediately.

4 . Stage

Pour mixture through a sieve or fine strainer into a bowl. Cover, and chill for several hours or overnight.
