Solved
Gourmet Cooking Skill Tree not Appearing
My Sim has Gourmet Cooking unlocked and can prepare Gourmet Cooking recipes normally, but the Gourmet Cooking skill does not appear in the Skills panel. Because the skill is missing from the UI, my Sim is unable to complete the Master Chef aspiration, even though the Sim is actively using Gourmet Cooking interactions. The game clearly recognizes Gourmet Cooking as unlocked and usable, but the skill itself is not being tracked or displayed.
Update: I was able to level up the skill after cheating to get the Gourmet Cooking skill to first level. Levels are progressing normally now!
