Cooking therapy: I made a vegetable stock. This also used the scale, as the mirepoix was determined by weight - two parts celery, one part each carrots and onions. I'll be using the stock tonight - some for the mashed potatoes and some for the sauce I'll use for the chicken breast fillets - fillets I cut off the chicken myself and froze. I feel very proud now.
Except I read the instructions wrong and I used too much celery.
Ah, it still tastes fine, and I'll do better next time.
