What are the rarest and most expensive food items on the game?

Question

I would like to know what are the rarest and most expensive food or edible items in-game. Those that are impossible to get from a NPC. I am interested in items such as the Crocodile Steak.

Answer 1

Foods which are expensive (Antica prices)

1. Dishes that we can make during the Hot Cuisine Quest, possible to get once per year. The event starts on August 1 and lasts a whole month (I will mention ony those more expensive)

• Blessed Steak(800/900k on market) 
• Hydra Tongue Salad (180-200k market) 
• Pot of Blackjack (180-270k) 
• Rotworm Stew(400-500k)
• Sweet Mangonaise Elixir(540-700k)
• Tropical Fried Terrorbird(160-200k)

        2. Rewards for completing A Piece of Cake. The A Piece of Cake event starts every year on February 21

• Blueberry Cupcake(700-800k market)
• Lemon Cupcake(500-600k market)
• Strawberry Cupcake(1-1.2kk market)

       3. Food which can be obtained during Orcsoberfest (I will mention ony those more expensive)

• Blue Gingerbread Heart (3-4.3kk market) 
• Green Gingerbread Heart(1-2kk)
• Red Gingerbread Heart(1-2kk)
• Candy Floss (500k-1kk)
• Tiny Bass (70-80k market) - We can catch it during the Fishing Time game during the Orcsoberfest Quest. It turns into a larger version or disappears when we try to fish again.

       4. Other food

• Northern Pike(90-180k market) - With a bit of luck, it can be caught in the ice hole in Svargrond. A very rare fish needed to complete a quest and for one stew in Hot Cuisine Quest.
• Crocodile Steak (120-180k) - Can be obtained using an Obsidian Knife on a dead Killer Caiman (but only during a tast Feed a Beast in An Uneasy Alliance Quest).
• Marlin (8-15k) - rarely dropped by Island Troll (0.07% chance) /Undead Jester (0.2% chance) / Thul (67% chance)
• Forbidden Fruit(3-4kk) -When we eat the fruit, we will get the Forbidden Fruit achievement. Can be looted rarely from The Enraged Thorn Knight

Answer 2

I think the rarest foods are three ice cream cones, which are impossible to obtain.

 Ice Cream Cone (Mellow Melon), this one was already a CIP reward for some tutors.

Ice Cream Cone (Sweet Strawberry).

Ice Cream Cone (Velvet Vanilla).
