This is basically a caker recipe for making creme caramel. This flan is super easy, delicious, and a complete cheat! We've had to make a couple of adjustments to this recipe. Typically the syrup that you would use for this is Karo dark syrup, but we can't really get that in Canada, so we had a not-quite-as-dark syrup. You can also make your own caramel for this, but we resorted to the syrup after ours seized in the pot twice, crystallizing solid.
This is a recipe you see in Mexico and Mexican communities a lot, and the lime juice spritz at the end really adds a lot to the flavour. The texture of this flan is a little springier and denser than the more "refined" French-style creme caramel, but it is really delicious and much less finicky.
