Is it ok to use Self Rising Flour way past the purchase date?

Self-rising flour may be used past its expiration date. In general, it's usually advised to use self-rising flour within a few months to 12 months of its printed "best by" date for the best quality and freshness. However, if stored properly in a cool, dry place in an airtight container, it can still be usable for some time.

You can check the quality of the flour by sifting it and looking for any clumps or discoloration. If there are no signs of spoilage, it should be safe to use, although the leavening agents (baking powder and baking soda) may not be as effective as they were when the flour was fresh. This can potentially impact the texture and rise of baked goods.

To ensure the best results, it's always a good idea to refer to specific storage instructions provided on the flour packaging or consult with the manufacturer for more information.
