Now on to the recipe but first some rhubarb information.
There are many varieties of this extremely tart fruit/vegetable. Most of rhubarb fall into two basic types, hothouse and field grown. Hothouse rhubarb is distinguished by its pink to pale red stalks and yellow-green leaves, whereas field-grown plants, which has a stronger flavor, have cherry red stalks and green leaves. Hothouse or field grown, either kind is the right kind! Rhubarb freezes super, so buy extra and get chopping.
Hothouse or Field Grown
Hothouse rhubarb is available from December to March, while the field-grown rhubarb can usually be found from March to October. The peak from season is from April to June. Choose crisp stalks that are brightly hued. The leaves should be fresh-looking and blemish-free. Highly perishable, fresh rhubarb should be refrigerated, tightly wrapped in a plastic bag for up to 3 days. Wash and remove leaves just before using.
