Celery bulb Root Salad

From the "Middle Eastern Vegetarian Cook book" Salma..

Celery Bulb root, peeled and washed.- julienne sticks
Kohlrabi - peeled and washed - sliced thinly
Chopped corriander

Dressing 1: (original from the book)
yoghurt, lemon juice, salt, mustard,- mix, dress and rest.

Dressing 2: (my preference)
Vinegar, sugar, salt, - mix, dress and rest.

This salad actually tastes better when it  can rest in the dressing for a while.  Will not go soggy but absorbs and develops quite a "bite".  Like pickles.

Sumac or nigella seeds or black sesame for garnish.
Very crunchy salad.

Surprisingly very nice!  The celery bulb was a new one for me.  Also doing something with Kohlrabi that was interesting was a plus too.
I later added carrots for colour and taste, Worked great!!
I'm guessing that any of your favourite "root" veggie would work wonders here.
Left on the table, the whole family just pecked at it randomly.
