Step 1

Put the cream and butter into a medium sized heavy bottomed saucepan and heat to a gently boil, stirring often so the cream does not scorch. Gently boil the cream, stirring often, until it is reduced by at least 1/ This may take up to 30 minutes, depending on your pan, and the heat of your burner. Note: I like to mark the depth at the start so I can judge when it has reduced enough. I dip a toothpick or popsicle stick into the cream and mark the measurement with a pen. Then I have a good reference point to check the progress of the cream.

Step 2

As the cream cooks down it will thicken, almost like a custard, and will coat the back of a spoon. Pour the cream into a shallow baking pan to cool. Put it in the refrigerator for several hours or overnight.

Step 3

Scrape the clotted cream out of the pan and into a small jar for storage. This recipe will make somewhere around 2 cups, and the clotted cream will last up to 10 days.
