4. 4

    (You will need to puree in batches.)
11. 11
    Process at the lowest speed until the tomatoes are pureed.
12. 12
    Pour in more liquid, a little at a time, until the tomato confit is the consistency of heavy cream.
13. 13
    Turn the speed up, and blend about a minute, until completely smooth.

    Transfer to a container, and repeat with the second half of the tomatoes.

16. 16
    Season with 1/2 teaspoon salt and some pepper.
17. 17
    Taste for seasoning.
18. 18
    The tomatoes need to fit snugly in the baking dish in one even layer.
19. 19
    If there is too much room in the pan, the sauce will be thin and lose some of its intensity.
