❓ Frequently Asked Questions

🤔 Common Storage Container Questions

Q: Can I put hot food directly into glass containers?

A: Yes, borosilicate glass containers can handle hot food directly from cooking. However, avoid placing extremely hot containers directly into refrigerators or on cold surfaces. Allow slight cooling (2-3 minutes) to prevent thermal shock to your refrigerator and save energy.

Q: How do I remove turmeric stains from containers?

A: For plastic containers, create a paste with baking soda and water, let it sit for 30 minutes, then scrub gently. For stubborn stains, mix lemon juice with salt. Glass and stainless steel containers rarely stain, but the same method works if needed. Prevention tip: lightly oil containers before storing turmeric-heavy dishes.

Q: Which containers are best for freezing dal and curries?

A: All three materials work for freezing, but glass and stainless steel perform best. Leave 1-2 inches of headspace for expansion. Glass containers can go directly from freezer to microwave (remove lid), while steel requires thawing first. Avoid freezing very liquid curries in plastic as it may become brittle.

Q: Are expensive glass containers worth the investment?

A: Quality borosilicate glass containers typically pay for themselves within 1-2 years through durability and versatility. They're ideal if you frequently reheat food, bake regularly, or want completely non-reactive storage. For basic storage without heating needs, good plastic containers offer better value.

Q: How long should food containers last in regular Indian kitchen use?

A: Glass containers can last 10+ years with proper care. Stainless steel containers typically last 5-10 years. Quality plastic (PP) containers should last 2-3 years with regular use, 1-2 years with daily microwave use. Replace sooner if you notice odor retention, staining, or seal failure.

Q: Can I mix different container brands in my storage system?

A: Yes, but consider standardizing base dimensions for efficient stacking. Measure your containers before buying new ones to ensure they stack properly. Focus on having 2-3 standard footprints that work well together rather than collecting many different sizes that don't optimize space.

Q: What's the safest way to transport food in containers?

A: Use lightweight plastic containers for travel and school/office lunches. Ensure lids are properly sealed and consider double-wrapping liquid dishes. For long-distance travel, glass containers in padded bags work well but avoid temperature extremes during transport.

Q: Do I need different sizes for optimal meal prep?

A: Yes, having 3-4 different sizes optimizes meal prep efficiency. Small containers (250-500ml) for individual portions and ingredients, medium (750ml-1.5L) for family meals, and large (2L+) for batch cooking. This variety reduces food waste and improves portion control.
