Steps
1 Done | Measure all the components, carefully wash the eggs and get ready to make the marshmallow fluff, if you don't have the commercial one. For such purpose, combine water, golden syrup and sugar and warm up the mixture until it reaches 115°C (240°F), that takes approximately up to 15 minutes over medium heat. Meanwhile beat the whites to soft peaks, adding the kosher salt and cream of tartar when the egg whites are still foamy. When the syrup mixture is ready, let it stand for 20 seconds and then slowly pour it into the beaten egg whites. Let this process continue for 7-8 minutes, but don't let the mixture get warmer than the room temperature. Pour your rum and keep mixing to the formation of medium-stiff peaks. |
