Use a coffee grinder to finely grind the chia seeds. Mix 1 tablespoon ground seeds with the lime/lemon juice and honey. Set aside to thicken.

Finely grate the orange zest of 2 oranges into a bowl. Use a sharp knife to remove the remaining rind and pith of all the oranges and discard. Slice the delicate orange segments from the membrane by carefully cutting like this. Chop the segments into small pieces then place in a bowl. Add the chia paste and mix until combined. If the marmalade is not thick enough add more ground chia seeds - 1 teaspoon at a time until desired consistency. Check sweetness adding more honey if needed.

Serve spread on toast - I served it with my current addiction milk kefir cheese - or spoon onto yogurt and sprinkle with granola. Store in the fridge and use within 1 week. It can also be frozen if you have loads of oranges to use up.
