belle de boskoop
The large, late season cooking heirloom of the highest quality is still grown commercially in much of Europe where it known and respected. It is found only occasionally in the US. Belle de Boskoop may be a bud sport of Reinette de Montfort. K.J.W. Ottolander, Boskoop, (near Gouda) Netherlands, 1856.
The blocky, green fruit is somewhat lumpy and largely patched and netted with russet. It only occasionally develops a brownish, reddish blush. The fruit can be exceedingly beautiful. The russet is a pretty typical golden russet color, and the blush is usually minimal. The basin can be furrowed and wrinkled but can also be nearly regular. The calyx can be open or closed: when open, it's very open. Ribs can be minimal but can also be rather pronounced.
This apple is highly recommended for chefs. It cooks up quickly and makes a yellow, soft, medium tart, tasty apple sauce. It also makes a very good pie apple. Currently growing at Super Chilly Farm.
