Thread: How do I make my crispy beef more crispy?

I have a simple method for cooking Vietnamese crispy beef. Prepare a quick marinade with rice wine, palm sugar, fish sauce, etc, and add two beaten eggs; then take some fillet beef, coat in the mixture, dry it slightly then dust in cornflour and deep fry in oil.

The meat is nice and tender and very tasty, but I'd like it to be more crispy... any ideas?
