Alot of people rip on the Blender tutorial series by Blender Guru, but I must admit, I learned so many techniques from doing this.
Following the Blender Guru Tutorial series on youtube. Learning how to create and shape basic forms
Adding materials and painting with weights
learning how to use instances of an object (sprinkles) so that they don't have to be individually modelled rotated and positioned
Rendering hard surface objects like glass cup and saucer above.
