Put water, salt, sugar, five spice powder and garlic in a large pot. Stir to mix well and bring to a boil. Add peanuts and mix well with liquid. Bring to a boil again; reduce heat to medium and continue cooking for 5 minutes. Turn heat off and leave peanuts in the pot for 1/2-1 hour, stirring 2-3 times; drain.
Preheat oven to 325 degrees. Spread boiled peanuts on Silplat lined baking sheet and roast for 30 minutes, stirring once or twice. Reduce heat to 250 degrees and continue roasting for 1 1/2 - 2 hours, stirring the peanuts once or twice, checking for brownness. Turn off oven, open the oven door for 5 minutes to lower the temperature, and leave the peanuts in the oven another hour or two, or overnight to crisp up.
