Made this today with 450g sugar.
Rind and flesh of two lemons, plus juice of half of another lemon, left off pith as don't have Meyer lemons.
Slight glitch, forgot eggs in first ten minute cook as someone came.
Let cool down then added eggs, and started again.
Will fridge tomorrow.
Very good recipe, and very yummy!
