Put the ricotta in a medium bowl. Finely grate the zest of the lemon over it, then halve and squeeze the lemon and blend in the juice. Stir in the shallots, scallions, olive oil, salt and a healthy pinch of pepper. Taste for salt and pepper, then stir in the herbs. Cover and chill for at least 1 hour before adjusting for salt, pepper and lemon juice and serving.
A dollop of this on a cracker or sliced baguette makes a good appetizer; more of it on dark bread with roasted tomatoes, charred lemons or sliced cucumbers makes a tartine; and a lot of it stirred into pasta makes a dinner.
The spoonable is best the day it is made, but you can keep it for up to 2 days tightly covered in the refrigerator. Stir well before using.
