1. Add the beaten eggs (with 1 egg white removed), rum, and vanilla together and mix well.
2. Add the flour, sugar, baking powder, lemon zest and salt together and blend well to mix.
3. Place the flour mixture on a clean work surface and form a well in the middle.
4. Add the egg mixture to the well.
5. With your hands, begin mixing the flour mixture into the egg mixture starting from inside the well and work out being careful not to break the walls of the well.
6. When everything is combined, keep scraping the board and kneading so as to bring everything together into a log of dough.
7. Knead the dough using your palm and rolling forward. As the log gets longer, fold it into thirds onto itself and continue kneading and repeating this process for about 10 minutes until the dough is smooth and uniform in consistency. It should be a stiff dough that does not spring back much when indented with your finger.
8. You can cut the dough into more manageable size logs. Put each log into a food safe bag, seal and let rest for about 15 minutes.
9. Then knead again for about another 5 minutes.
10. Let the dough rest covered in the bags over night.
11. When ready, cut the dough into small discs. We used 100gm per disc but you can use less if you would like smaller frappe. Keep the rest of the dough covered at all times.
12. You are going to work the dough through a pasta maker as you would when making pasta dough. Start at the widest setting and pass the dough through each of the settings ending with the most narrow setting. This step is most important to get that thin, crispy texture.
13. You will now have a long panel of dough. Lay this flat on your work surface and with a fancy edged pastry cutter, cut the panel into 3 long ribbons.
14. You are going to form a rosette shape with each of the ribbons of dough by forming them into a circle and pinching the edges of the dough together as in the video and photos.
15. Cover the completed rosettes with food safe plastic until ready to deep fry. If you are working alone, work in batches so that the rosettes do not dry out before frying.

For deep frying

1. Place about 4 inches of vegetable oil in a pot and heat to 350F. Carefully place 1 frappe at a time into the oil. It should immediately sizzle up and almost double in size. As soon as it is lightly coloured, remove from the oil with a slotted spoon and place upside down on a paper towel lined pan. Be careful not to stack too many onto each other as they will break apart.
2. Once they are cooled and when you are ready to serve them, sprinkle them lightly with icing sugar and arrange on a platter.
