PASTA QUILLS TASTE LIKE COPPER WIRES

WAS COOKING ON VALENTINES DAY A PACK OF FATTIS & MONIS NOT REALISING THAT THE FOOD WILL BE SPOILED BY AN AWFUL TASTE OF COPPER OR METAL OR WHAT, BUT IT WAS SO BAD HAD TO THROW THE FOOD AWAY. I CHECKED EXPIRING DATE IT SAID 2018, SO I DONT KNOW WHAT COULD BE THE REASON OF THIS TASTE. I HAVE USED THIS PRODUCT MANY TIMES BEFORE THIS IS THE FIRST TIME IM EXPERIENCING THIS.
