Celeriac and Kohlrabi fritters

Hi all things going ok here experimenting with veg today and flavours and found a recipe on line to try but change as I do
So what do you need for this very yummy and slight work recipe
now as I rarely measure it's not an easy recipe to give all measures and some times need to use your instincts
 You will need roughly

Half a medium celeriac grated finely
1 medium kohlrabi grated finely
3 egg mixed
Salt and pepper to taste
Small bunch coriander chopped
1 tbsp chilli flakes (optional)
1/2 cup flour and quarter cup Panko bread crumbs
4 spring onion finely chopped

Mix this altogether till form balls in your hand or can stick it in blender like i did and pulse till nice mixture...
it is quite a delicate mix and needs gentle cooking
It may even appear wont hold but be very gentle with it when tuning and hold very well
Cook on medium heat until golden brown both sides and cooked through
