Here are the items which I choose to make myself from scratch and the items that I prefer to buy while I prepare my everyday meals:

• Yoghurt - I Make, it is easy to make and tastes better, also store bought turn out to be expensive
• Ghee - I Make, homemade ghee tastes better than any brand of store bought ghee
• Paneer - I Buy, as I use paneer only once a week, I prefer to buy and use
• Chapati - I Make, there is nothing in comparison to homemade hot rotis/chapatis
• Bread - I Buy, it is a complex process to make, requires lots of time
• Pizza crust - I Make, it turns out to be more soft than store bought
• Pizza sauce - I Make, turns out tasty and original flavor
• Pasta sauce - I Make, easy to make and turns out to be much tastier
• Spices - I Buy, find a good brand that suits your taste and buy the same
• Ginger/ garlic paste - I Make, easy to make and no preservatives as present in the packaged ones
• Pickle - I Buy, unless you have time and perfect masalas for making it
• Dips and chutneys - I Make, prepared in minutes
  
• Soup - I Make, always prefer the original home made soup
• Stock/ broth - I Make, healthier and without any chemicals added

Items which I use very less, I usually prefer to buy it and use rather than going through the hassles of making it.
