help - how to thicken custard

[BananaGio]

made custard for s Delia trifle- it's now cooling and is thickish but still pourable- want it to get more to that ambrosia custard thickness- any tips?

bumping but can't help, sorry!

Cornflour?

is it birds powder or real with eggs?

if real with eggs you could add another egg and reheat
if with custard powder mix a teaspoon more powder with a very little milk and whisk that in and heat it up
or similarly just mix some cornflour with a little water/milk and add that

with real eggs
ok will try with another eggs
fingers crossed! thanks

thanks for answers yesterday. used an extra egg and bit of cornflour and was fine
