Blizzard Chizzard Gizzard can be obtained by Blizzard Chizzards of course, either by killing them or taming them and harvesting from them after they have become your Pets.
Blizzard Chizzards are defensive blue-white dragon-chicken-like creatures spawning on Snow during the (ingame) day. They can be found in Taiga-biomes, snowy Tundras, Frozen Deserts and frozen Oceans, also sometimes high up in the Mountains or Canyons.
Since update R25, Blizzard Chizzard Gizzard can be made into Questionable Jerky 1:1 each by putting it into a Forge together with some Fuel. This jerky is used for cooking Food in a Cooking Station.
Raw Blizzard Chizzard Gizzard is no suitable cooking ingredient.
On the other hand, Blizzard Chizzard Gizzard is a necessary ingredient in some Crafting Recipes like for Fire Resistance Potions, Freeze Bombs, Speed Potions and Holiday Music Boxes.
This crafting material cannot be put into your quickbar and cannot be placed into the game world. It also cannot be displayed on any display containers.
