@spotiche5- Yes, I have made Thai crab cakes and also had them at a Thai restaurant with lemon instead of lime juice. I think that lemon goes perfectly with this dish, but I think it is also important to pair it with certain ingredients while using others sparingly.
Since this recipe also often calls for ginger, you should definitely include this spice in the crab cakes when you use lemon. The two flavors compliment each other nicely, and give the crab cakes a nice balance of spicy and tangy undertones.
You should also go light on any sweetness you add to your Thai crab cake recipe, such as brown sugar like the article suggests. Too much sweetness along with lemon will give the crab cakes a strange flavor, in my opinion.
Also, don't forget to use spices along with the lemon juice. Pepper and cilantro both go perfectly with the flavor of lemon in these ethnic crab cakes.
