A variation of the previous dish with salmon sausage, chocolate rye pumpernickel (in pudding form), micro leeks, and oca.
50g charred leeks, cooked through
30g pumpernickel bread, trimmed of crusts and crumbled
15g neutral oil
Place all of the ingredients except the oil in a blender or food processor and blend until smooth. Slowly drizzle in the oil with the motor running. If necessary, add more oil to thicken, or water to thin. Adjust seasoning.
Oca (Oxalis tuberosa) is a species of oxalis that has long been cultivated in the Andes, where it is the second most popular tuber next to the potato, and more recently in New Zealand. Unlike common oxalis (wood sorrel), oca forms prolific fleshy tubers that can be eaten raw or cooked. In its raw form, they are crisp and moderatly acidic, like an apple without the sugar.
Oca contains fairly high concentrations of oxalates, an organic acid that can lead to kidney stones. Because the oxalates are found mostly in the skin, they can be diminished by peeling, cooking, or by exposing the tubers to direct sunlight for several hours.
Cultivating oca requires a long growing season. To get a headstart, they were sprouted in a bright, moist environment. And now that they're off to a good start they'll go directly into pots, where they'll live until the ground warms up. By late autumn, I hope to have a new crop of these delicious nuggets.
