Deducting Values from SQLite using Cursor

I have a cursor that contains the results of a query which returns the a list of ingredient names and their corresponding measurements from an SQLite database.

I am trying to implement a function that will deduct these values from another table when a button is pressed.

I am having some trouble trying to implement this function using the cursor values. Can I just pass the cursor into the function or should I be putting the cursor into a list and then passing the list variables into the function?

Below is the code I have so far but if anyone can point me in the right direction that would be great.

Cursor

   final Cursor ingredients = adapter.getRecipesIngredients(recipeCode);

getRecipeIngredients Function

public Cursor getRecipesIngredients(int code)
{
    return db.rawQuery("select _id, ingredient_name, measurement from ingredients where recipe_code = " + code, null);

}

Button code with function

    Button cookButton = (Button) findViewById(R.id.cookButton);
    cookButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            while (ingredients.moveToNext())
            {
                //how should I be passing the cursor into the fucntion?
                adapter.deductIngredient(ingredients);
            }
        }
    });

SQL function to update table

//deducting ingredients after cooking
public boolean deductIngredient(String ingredient, int measurement)
{
    db.rawQuery("update kitchen set kitchen.measurement = kitchen.measurement - "+measurement+" where kitchen.ingredient_name = "+ingredient, null);
    return true;
}
