Heat your stove and a pan with a layer of water over medium-high heat and bring to the boil.

Note down the weight of Phase A including the measuring cup, so that we can top up the evaporated water after heating.

Check the temperature. Once Phase B reaches 70 degrees Celsius, weigh it and top up the lost water content until you reach the desired weight as noted earlier. You may add a little more water so that less is lost during evaporation.

Pour Phase B into Phase A followed by Phase C and mix with a stick blender. Pulse for 5-10 seconds or until it turns white, which is an indication that the mixture has emulsified.

When the temperature is 40 degrees Celsius, start adding the cooling phase. Start with Phase D, followed by E and F.

Measure the pH. Use an acid such as Lactic acid solution to lower the pH or a base such as Sodium bicarbonate solution to raise it until you reach the desired pH of 5.5.
