She's mad because I ruined her masterpiece.

Yesterday, my girlfriend was cooking her favorite dishes and I was so excited to taste everything. She was very serious doing her work, and I felt the urge to help her. When I did, I messed some of it and she got mad. She walked out and I tried to chase her. She wonít talk to me the whole day until this morning. How should I make up to her? Should I cook her a foreign cuisine? However, Iím bad at cooking. What should I do?
