I use those to finish building out 6 first ovens. This means I get three of the second oven built just through requests and gifts although I do use my collectables if I need like 2-3 more parts towards the end of the day when I know I've gone through all my requests and gifts. Then I slowly work up to getting 6 of the second oven built as I work on the goals since they require so many servings anyway.
So basically my build goes like this: 4-5 (first oven) -> 3 (second oven through requests/gifts) & 5-6 (first oven through collectibles) -> 6 (second oven).
I don't use a timer to make sure everything is right on time but I do check my recipes within 1-2 hours of when they're finished. So I never spoil any recipes and I don't lose too much time in between current and next set of recipes.
