Pork Floss Swiss Roll

This recipe is adapted from "Elegant Swiss Roll by Kelvin Chai". The roll is soft and fluffy. Taste wise, it's sweet and savoury at the same time. My brother found the taste weird but I liked it. :P
Here's the recipe (with my adaptations in pink)
What you need
For the cake

• 4 eggs
• 70 gm castor sugar (i used 50 gm)

• 80gm plain flour (i sifted twice)
• 50gm melted butter (i used canola oil)

For the filling

• 100gm buttercream
• 50gm mayonnaise
• 50gm chicken floss (i used pork floss)
