Pre dissolve ½ teaspoons or half a packet of agar agar in a medium saucepan with 1 ⅓ cup of water and ¼ cup of sugar. Pour dissolved agar agar into gooseneck kettle and slowly start pouring over the filter, straight down the center at first. Once water rises up, pour to the sides of the coffee in a sort of elliptical massaging pattern. Let sit for 1-2 minutes until all the water has filtered through. Use hot water to knock the grounds off the sides of the filter and continue the elliptical pattern until there is 500g of coffee. Let sit for another 1-2 minutes and remove the filter.
