✔If your kataifs are not covered with bubbles then that means your batter is too thick and you need to add more water. Do so in 1/4 cup additions, whisk and try again.
✔Placing the kataifs in kitchen towels right after taking it off from heat is very important as it will soften the kataifs making them easier to seal. It will also prevent them from drying. If your kataif become dry you will not be able to seal them.
✔Once the kataif cools down fill them immediately, otherwise it will dry out making it difficult to seal.
✔ For the thick cream i used kdd cream you can also use Nestle thick cream or any thick cream which you can get hold of. But do not use whipping cream or cooking cream.
