Refrigerator Pickles

One of my friends introduced me to these pickles: The onions are also great to eat on sandwiches...can't wait for these to finish pickling, so I can start eating them!

So here's the recipe:
1gallon sliced cucumbers
3 white onions

Slice in jar alternating until jar is filled
On the stove in a saucepan

4 cups apple cider vinegar
4 cups sugar
1 1/2 tsp mustard seed
1 1/2 tsp celery seed
1 1/2 tsp turmeric
1/3 cup salt

Stir and bring to a boil. Boil until sugar is dissolvedPour sauce over cucumbers and onions and let cool. When cool put lid on jar and refrigerate. Shake and stir jar with cucumbers for 5 days. Keep refrigerated.
