Before we grab the Golden Leaf, our inventory looks like this:
Item (Item ID)
Peachy Peach 176
Shooting Star 130
Cake Mix 172
Volt Shroom 135
Mystery 163
Jammin' Jelly 156
Ruin Powder 137
Maple Syrup 155
Ultra Shroom 150
Ice Storm 131
-----------------
Hot Sauce 173
Hot Dog 159
Mystic Egg 168
Honey Syrup 154
Fire Flower 132
Mushroom 148
Life Shroom 151
Inn Coupon 164
Turtley Leaf 174
Horsetail 175

As a result, we need to sort in order to replace the Inn Coupon/Horsetail with Golden Leaf. I've determined that sorting by "Type Descending" is the best, resulting in the following:

Peachy Peach 176
Horsetail 175
Turtley Leaf 174
Hot Sauce 173
Cake Mix 172
Mystic Egg 168
Hot Dog 159
Inn Coupon 164
Mystery 163
Ruin Powder 137
-----------------
Volt Shroom 135
Shooting Star 130
Ice Storm 131
Fire Flower 132
Jammin' Jelly 156
Maple Syrup 155
Honey Syrup 154
Life Shroom 151
Ultra Shroom 150
Mushroom 148

From here let's say that we toss the Horsetail (Less menuing!)

Golden Leaf 169
Peachy Peach 176
Turtley Leaf 174
Hot Sauce 173
Cake Mix 172
Mystic Egg 168
Hot Dog 159
Inn Coupon 164
Mystery 163
Ruin Powder 137
-----------------
Volt Shroom 135
Shooting Star 130
Ice Storm 131
Fire Flower 132
Jammin' Jelly 156
Maple Syrup 155
Honey Syrup 154
Life Shroom 151
Ultra Shroom 150
Mushroom 148

Then we can use the Life Shroom for Shroom Roast and toss the Inn Coupon

Shroom Roast 180
Golden Leaf 169
Peachy Peach 176
Turtley Leaf 174
Hot Sauce 173
Cake Mix 172
Mystic Egg 168
Hot Dog 159
Mystery 163
Ruin Powder 137
-----------------
Volt Shroom 135
Shooting Star 130
Ice Storm 131
Fire Flower 132
Jammin' Jelly 156
Maple Syrup 155
Honey Syrup 154
Life Shroom 151
Ultra Shroom 150
Mushroom 148

We could make Meteor Meal after and just keep the Shooting Star... But may want to free up inventory. This is just a possible suggestion!
