Scaling Issue

I’ve been creating 3D art with Poser and DAZ Studio since 2009. I recently started a new journey learning how to create my own content for DAZ Studio using Blender. Suffice it to say, the learning experience is proving quite challenging.

I’ve been following a tutorial series by BlenderGuru on YouTube for the last couple of weeks, and have been stuck at one point in a lesson for the last four days now. Frankly, I’m at my wit’s end.

The series teaches beginners everything from navigation basics to modeling and rendering a couple of sprinkled doughnuts on a plate with a cup of coffee. I’ve modeled the doughnut, and now I’m trying to model the cup.

Here’s where I’ve hit a wall, and need help… erm… scaling (sorry)… it. I’m supposed to be able to scale the base of the cylinder I created so it roughly matches the narrow base of the cup in the reference photo I’m using. The trouble is, Blender keeps scaling toward whichever vertice I select, making my cylinder stretch at angle. To make matters worse, my head is stuffed with so much info about Blender’s functions that I have no idea what I may be doing wrong or how to fix it.

From the front, the scaling looks fine:

But from any other angle, not so good:

How do I scale the base inward without pulling the mesh toward whichever vertice I’ve ALT+Click’ed on?

I hope that this image helps.
