Take a zestester, thumb on the butthole, base of the microplane on the top of the lemon, and just pull around.
Blanch all your citrus in boiling water for 1 minute before removing and saving the leftover liquid.
Cut all your lemons and limes in half and give them a thorough juicing.
Add your sugar and your lemon zest back to your lemon water.
Bring that to a simmer before adding in your lemon juice and bringing to a simmer again.
After one final pass through a strainer, your cordial is done.
Keep that in the fridge. It will last for months.
Mix it with your favorite sparkling water and you have an incredible summer
