Hi,
I had two unmarked jars in the refrigerator. One was ginger syrup leftover from making candied ginger and the other was used peanut oil waiting to fry another day. Both jars had been in the refrigerator for several weeks, both looked like chilled peanut oil. To tell the difference, one might need to sniff the contents.
I made falafel batter, which we cooked as we wanted it. My Dad was home alone. He decided to make himself some falafel. He ran into a wee problem: the oil in the fryer was boiling. He decided plop the balls that never quite fried into the vat. Whatever glop the falafel emerged as he ate.
Yep, my Dad attempted to fry falafel in ginger syrup. He said the texture was weird, but the taste was delicious.
I'm inclined to believe ginger syrup can last quite a while in the refrigerator. I have mixed it with soda water with ice for a drink. I have contemplated making ice cream with it, though I have not yet. Rene G had the experience at Matchbox of a cook pouring a glaze of ginger syrup over an unfrosted Old Fashioned apple fritter. He reported it was very good.
Regards,
