Stupidly, I did not note when exactly I planted these potatoes, known as les rattes. Fingerlings. But it was late April. From potatoes that had sprouted. By early May the first leaves had poked up above the ground and I started mounding earth up against their stems.
I dug them up on the 4th of July (so about 8 weeks after planting) and we ate the first ones that night in a Niçoise salad, with quick-pickled beets, and arugula and lettuce leaves, purple basil and chives from the garden, plus the obligatory eggs.
They have a firm, waxy texture and very good, slightly nutty flavour. The second portion was eaten as a potato salad with mayonnaise and crisp celery heart (try and find organic celery - it is one of the most sprayed crops out there, as it is is a bug magnet), and I'll pan-roast the last batch. If I can stand to turn on anything that generates heat. It is very hot and very muggy.
