Tea, coffee and milk — separately
This is rich in plant iron. Tea, coffee and dairy at the same meal noticeably lower its absorption — have them an hour before or 1–2 hours after.

Meat or fish helps
Meat and fish proteins at the same meal boost plant iron absorption.

A source of vitamin C
Pair it with buckwheat, legumes or greens — vitamin C boosts plant iron absorption.

Eat it with fat
Carotenoids are absorbed much better with fat: add oil, sour cream or nuts.

Its calcium is barely absorbed
Oxalates bind calcium: about 5% is absorbed versus ~30% from milk. Boiling and draining lowers oxalates.
