Some recipes do not appear in the Cooking Table's search, even when the necessary tools and ingredients are present. I noticed this with both the Ketchup and Mustard items from Pam's HarvestCraft 2: Extended Food Core for Minecraft 1.16.5, and I'm sure it effects a few other recipes as well. The large majority of recipes appear without issue, both in the #NoFilter book and in the Cooking Table.

For the Ketchup, I specifically had tomatoes in my fruit basket connected to the Cooking Table and a Tool Rack containing the Juicer, yet I could not craft Ketchup in the table, which is the Juicer crafted with a single tomato. Ketchup also does not appear when searched for in the #NoFilter recipe book. Not appearing in the book also happens with Mustard.
