Once combined, add in your Fish Sauce, Lime Juice, and enough water to thin out the curry to make it a sauce and not a paste. Whisk together to fully incorporate the water. The sauce will thicken up when you cook it, so it's okay to error towards too much water.
Heat your pan over medium heat, once warm add your sauce, and allow it to come to simmer. Once simmering add in your veggie and meat and allow to cook over medium to medium-low heat till cooked through. If you are using Paneer add when there is only a minute or two left as it will fall apart if cooked too long.
If all you have is a can of Full Fat Coconut Milk you can sub that in and decrease the added water. Do not make this with Light Coconut Milk or Coconut Milk Beverage as the Cream is missing in those.
