That is the way it has always been.

After H&H they now have added an upgrade to the cooking station that locks out some items you used to be able to craft like sausages until you have turnips and can upgrade the cauldron.

Haven't got any serpents yet so not sure where that falls into the mix. I assume they require the upgrade too for serpent stew. <if not something else, not quite there yet post updates.
