Step 1

Preheat the oven to 180 F.

Step 2

Pour the cream into a large oven dish. The dish should be big enough so that the cream sits over a wide surface area and be between ½- to 1-inch in depth.

Step 3

Put the cream in the oven for 12 hours.

Step 4

Remove the cream from the oven. A thick skin should have formed over the top.

Step 5

Let the cream cool to room temperature, then put the dish in the fridge for 12 hours.

Step 6

Scrape off the thickened layer that has formed and transfer to a mixing bowl. Discard the liquid.

Step 7

Mix thoroughly until you have a smooth, thick clotted cream.
