Optional step: Place anchovies in a stainer and shake to remove powder. This is not required but gives a cleaner texture.
Pre-heat a non-stick pan. Add vegetable oil.
Optional: You can add garlic with oil and cook for 30 seconds. But I personally skip garlic often.
On lower medium heat (e.g. 4 our of 9 levels) cook anchovies while stirring frequently. Be patient and cook until anchovies turn golden and completely dry and slightly crispy. If you do it on too high heat, it will burn.
Turn off the heat. Add water, soy sauce, sugar and mix thoroughly.
Turn back on the heat. On low to low-medium heat, melt all the sugar without burning.
Turn off the heat. Add mulyeot (korean malt syrup), roasted chopped nuts (optional) and sesame seeds.
Transfer to a airtight container immedicately as they will get harder and clump together as they cool.
Store in a freezer and thaw out or microwave for 10-30 seconds before serving. (But do not over microwave. It will burn the anchovies fast.)You can store in the fridge for about a week or in a freezer for months.
