Pickled walnuts used in recipes, commonly cooked in beef dishes. Pickled walnuts are made from the fruit of both common walnut tree varieties: "Juglans regia", the Persian, royal, English or common walnut, and "Juglans nigra", the black or American walnut. The first stage is to pick the walnuts whilst they are still green and before the shells have set. Most recipes say that late June is about the best time to pick them. The soft walnuts are then soaked in brine (salt water) for at least ten days. The walnuts are then drained and left to dry in the air. Soaking the
Fruit tree pollination a pollinator tree. Working from an old Spanish variety, "Tuono", researchers in 2008 started making available new self-fertile varieties that more closely match the qualities of the popular "Nonpareil" almond—including varieties "Lone Star" and "Independence". While self-fertile trees do not require pollen from a second tree variety for fruit / nut set, they still depend upon insect pollination for good production. Almond growers with self-fertile almonds report excellent nut set with half (or less) the number of bees in the field. Like apples, pears are self-incompatible and need to attract insects in order to be pollinated and produce fruit. One
