Brewing Recipe accepting any ingredient

I have a brewing recipe with the following code but the issue is that it's accepting anything as an ingredient

package mod.trianglesinpoo.mcores;

import javax.annotation.Nonnull;

import net.minecraft.item.ItemStack;
import net.minecraft.potion.PotionUtils;
import net.minecraft.potion.Potions;
import net.minecraftforge.common.brewing.IBrewingRecipe;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
public class brewrecipe implements IBrewingRecipe{
	private static final Logger LOGGER = LogManager.getLogger();
	    private static final ItemStack INGREDIENT = new ItemStack(ItemHolder.CRYOEXTRACT.get());
	    private static final ItemStack OUTPUT = new ItemStack(ItemHolder.CRYOCOCKTAIL.get());


	    @Override
	    public boolean isInput(@Nonnull ItemStack stack) {
	        return PotionUtils.getPotion(stack) == Potions.WATER;
	    }
	    @Override
	    public boolean isIngredient(@Nonnull ItemStack ingredient) {
	        return INGREDIENT.getItem() == ItemHolder.CRYOEXTRACT.get();
	    }

	    @Nonnull
	    @Override
	    public ItemStack getOutput(@Nonnull ItemStack input,@Nonnull ItemStack ingredient) {
	        if (isInput(input) && isIngredient(ingredient)) {
	            return new ItemStack(ItemHolder.CRYOCOCKTAIL.get());
	        }
	        return ItemStack.EMPTY;
	    }
	}
