Tips
Sauté garlic cloves with tomato for extra flavor
Prepare both chutneys ahead and store separately for convenient assembly
Use fresh vegetables and assemble immediately before serving for best texture
Good to Know
Chutneys may be refrigerated separately for up to 2 days; assemble fresh when ready to serve
Prepare both chutneys and chopped vegetables up to 4 hours in advance; store in separate containers
Serve immediately after assembly with coffee or tea
Common Mistakes
Prepare chutneys too thin: grind to thick paste to prevent sogginess
Assemble too far ahead: vadai will absorb moisture and lose crispness
Omit lemon juice: it brightens flavors and prevents pastes from tasting flat
