This could be all in passé composé, depending on the context.
My mother made a dish for a specific event, and I never tasted it. (passé composé)
I never used to taste the dishes that my mother used to make. (imparfait)
This one tripped me up too. The difficulty is that English doesn't always fit neatly into tenses like the romance languages. "Used to make" would have made it plainer.
Je n'ai jamais goûté ce que ma mère a préparé. Accepted :)
