I'm a litttle weird.
1) I spent several years working in a kitchen (upscale restaurants) in highschool... it's where I learned to cook... and it's my "I need a job" fall back job. I can cook anything.
2) I started college when my son was 2mo old (in my mid twenties), and my husband started shortly thereafter (this means that after tuition was paid we lived off of about 10k per year for several years)
I don't cook from scratch for moral reasons... I cook from scratch because I'm able to AND it's cheap, and I'm a super taster. I know what food costs are in restaurants, and am ALMOST constitutionally incapable of paying for something I can make at home for less...
Here are the things that I buy premade:
- bread (my dad bakes... yes: flour, yeast, oil, salt are cheaper than bread... I out and out refuse to bake my own bread. It's faaaar too many added hours of prefermenting, proofing, punching, kneading, baking or boiling. I'm including bagels and muffins in this group)
- Stovetop stuffing (addicted. I can make posh stuffing, I prefer theirs!)
- Noodles (I don't own a pasta machine, and am NOT rolling that stuff out by hand more than once a blue moon)
- Cereal
- Cake Mix
- Crackers
((Notice the "I'm not messing with grains" & baking business. Proteins and veg I'll mess with... I CAN make crackers, bread, stuffing, all that jazz. But I just out and out refuse.))
- Hershey's Chocolate Syrup
- Campbells Soup ((I have about 2 dozen soups I make from scratch, but campbells is inimitable))
- Stewed Tomatoes, Mayonaise, Mustard, Catsup, Pickles, etc. I CAN make these. I prefer not to make anything I need to jar. :P HATE canning things. I'll make things to freeze, but I really hate canning/jarring. I'll make jam once a year. No more.
- Trader Joes Orange Chicken, Chimichurri Rice, fried rice, roasted red pepper and tomato soup.
- Butter (not churning it, thank you... it's less expensive to buy it than to buy cream), nor do I make Cheese, & other dairy products. I'll make whipped cream. That's it.
That's about it. Everything else I make from scratch. I spend between 2-4 hours a day cooking, nearly every day. On average I cook from scratch for every meal (excluding the things above like bread for sammies) 300 days a year. We eat cereal or throw something premade in to heat up ABOUT once a week or every other week (aka between 30-52 days), and I usually go on "strike" a couple weeks a year where I refuse to cook for a bit.
I DO NOT THINK that there is "too much" or "too little". It's whatever works for your family!!! I happen to be trained in cooking, so I can do it reeeeally fast (I've always had good knife skills). I'm willing/able to schlep out to 5 different stores for the best prices on things. So I cook almost everything from scratch all the time. Working, staying at home, whatever.
