what is the difference between broccolini and broccoli rabe?
Broccolini is actually a HYBRID vegetable, a cross between broccoli and Chinese broccoli that was invented in 1993. ... This broccoli rabe is not as large and leafy as normal-wintered broccoli rabe, but the leaves and stalks are more tender and less bitter; the vegetable has to produce extra sugar in order to not freeze.
