Korokke (Japanese Croquette) is by far my favorite food that my mom makes. Every time I go back to my home in Japan, or when my mom visits us, I always request her to cook Korokke for me. My mom makes her Korokke without recipes so this is my original recipe that I have developed over the past years, learning from both my mom's method and adjusting the taste and texture to my preference. The Japanese usually enjoy Korokke with Tonkatsu sauce but the Taiwanese use ketchup. Try both and let me know what's your preference.
